RX 9/10 Restore Selection button access

Hi there,

I've managed to cobble together a working script in Soundflow over the last week from bits of code I found in other threads relating to RX.
The script is designed to automate a sequence of manual operations I perform nearly everyday on a series audio files, to prepare them for further manual work.

The sequence consists of running two module chain presets on each file, in series (not parallel), one after the other. (The reason for series is I use several instances of the External Plugin module which I have found will often get confused and load the wrong external plugin if another instance is running on a different file at the same time.)

However, after running the first Module Chain preset on each file, with the entire file selected I use RX 9's Restore Selection feature to bring forward the 'Initial State' of the entire file into its Undo History. Essentially this 'resets' the file to that initial state whilst keeping the all the history of the first Module Chain's operations. Next I run the second Module Chain preset which is like a 'B' to the first preset's 'A' and this creates a kind of A/B setup within RX's Undo History panel, looking like this:

Or folded down like this:

So then I can make a selection as I work, and restore that selection to the first or 'A' Module Chain's output to utilise the different version of processing. I'm not sure if iZotope figured the feature would be used like this but it works perfectly for me.

Currently, my script does everything I need except the Restore Selection action, as I'm not sure how to access this button:

I currently run 1 version of the script, do the Restore myself manually for each file, and then run a 2nd version to do the 2nd preset.
Here's the script (I'm sure lots of it will be familiar to anyone who's seen other RX forum posts):

sf.app.launch({
    path: "/Applications/iZotope RX 9 Audio Editor.app",
});

sf.ui.izotope.appWaitForActive();


function ensureModuleChainIsOpen() {
    var win = sf.ui.izotope.windows.whoseTitle.is('Module Chain').first;
    if (!win.exists) {
        sf.ui.izotope.menuClick({
            menuPath: ['Window', 'Module Chain']
        });
        win.elementWaitFor();
    }
}

function selectModuleChainPreset(name) {
    var btn = sf.ui.izotope.windows.whoseTitle.is('Module Chain').first.groups.whoseDescription.is('Module Chain Panel').first.popupButtons.whoseDescription.is('Preset').first;
    if (btn.value.invalidate().value == name) return;
    btn.elementClick();
    sf.keyboard.press({ keys: 'enter' });
    while (true) {
        sf.engine.checkForCancellation();
        if (btn.value.invalidate().value == name) break;
        sf.keyboard.press({ keys: 'down' });
    }
}

function processOpenModuleChain(numentries) {
    let mainWindow = 'RX' + sf.ui.izotope.activeBundleID.slice(-1) + " Main Window";
    let undoHistoryItems = sf.ui.izotope.mainWindow.groups.whoseDescription.is(mainWindow).first.groups.whoseDescription.is("Undo Panel").invalidate().first.radioButtons
    let currentUndoHistoryIndex = undoHistoryItems.map((button, index) => {
        if (button.isCheckBoxChecked) return index
    }).filter(button => button)[0]
    while (true) {
        if (currentUndoHistoryIndex >= numentries) {
            
            /* if (numentries === 19){
                code to bring forward

            } */
            throw 0;
    } else {
        sf.ui.izotope.windows.whoseTitle.is('Module Chain').first.groups.whoseDescription.is('Module Chain Panel').first.buttons.whoseDescription.is('Render').first.elementClick();
        break;
         }
    }
}

function nextFileWhenRenderWindowHasClosed(numentries) {
    while (true) {
        if (sf.ui.izotope.windows.whoseTitle.endsWith('wav').first.groups.whoseDescription.is("Task Progress View").first.exists) {
            log("processing")
        } else {
            sf.ui.izotope.menuClick({
                menuPath: ['Window', 'Next File']
            });
            processOpenModuleChain(numentries);
        }
        sf.wait({ intervalMs: 5000 })
    }
}


/**
* @param {string} name
* @param {number} numentries
*/
function processModuleChain(name, numentries) {
    sf.ui.izotope.invalidate();
    sf.ui.izotope.appActivateMainWindow();
    ensureModuleChainIsOpen();
    selectModuleChainPreset(name);
    processOpenModuleChain(numentries);
    nextFileWhenRenderWindowHasClosed(numentries);
}

processModuleChain('BGI-16,-3.1,New', 19);
//processModuleChain('BGI-16,-3.1,Legacy', 21);

So basically, I need to insert a bit that does the Restore Selection action where I've got the commented out bit in here:

 while (true) {
        if (currentUndoHistoryIndex >= numentries) {
            
            /* if (numentries === 19){
                code to bring forward

            } */
            throw 0;
    } else {
        sf.ui.izotope.windows.whoseTitle.is('Module Chain').first.groups.whoseDescription.is('Module Chain Panel').first.buttons.whoseDescription.is('Render').first.elementClick();
        break;
         }

Then I'll need to configure it to switch to the 2nd preset.

I've been incredibly impressed with the support offered here from Soundflow crew, providing people tailored scripts for people and their needs. I wanted to see how much I could do myself before seeking help, and I'm really glad to have spent the time putting my script together so far so in order to learn how SF works and be able to create my own macros in the future hopefully.

Hopefully this thread can help other people needing similar actions in RX, especially the Restore Selection button as I don't think it's been asked about here before?

Thanks in advance to anyone who can offer some help!
