What am I missing trying to repurpose Logic knob script?

What I'm trying to solve:
I'm trying to resolve the distinction that the current SF-Logic package has with respect to putting the Zoom +- sliders on Streamdeck+ knobs, and the fact that the current SF implementation ONLY targets the Track window, when Logic puts a different set of Zoom sliders on the Piano Roll view, that aren't addressed by the current SF-Logic package (afaict).

What I've tried so far:
Take a generic Knob macro, present in the SF Basics package, unpack its js and paste Pick js to that with appropriate parameter modifications. While I was able to generate Pick data, I don't appear to be getting any js from the Basics package that I can work with (see below, from a Generic Knob Command package macro js extraction):

//Calling command "<3>" from package "Basics" (installed from user/pkg/version "srAasovvDiQacRZ2mcId4RrOA8R2/ckuxffxq80000u010m7g02u3l/clycxeqx60000hy10jnc4f8zj")
sf.soundflow.runCommand({
    commandId: 'user:ckuxffxq80000u010m7g02u3l:clkv1kl7f0000np10izwlbmao#cm0a61g8s0004vw10fyzvr3o5',
    props: {}
});

sf.ui.logic.mainWindow.groups.whoseDescription.is("Piano Roll").first.groups.whoseDescription.is("Piano Roll").first.sliders.whoseDescription.is("Vertical Zoom").first.children.whoseRole.is("AXValueIndicator").first.mouseClickElement();

....or this...

//Calling command "Zoom Sliders - Adjust - Horizontal Zoom -5%" from package "Logic Pro" (installed from user/pkg/version "uOwKfD26NbWKAWotin3dmnSne7B3/cli50xtc200015210vyksy31z/cly64m6na0004m210xs4aihkd")
sf.soundflow.runCommand({
    commandId: 'user:cli50xtc200015210vyksy31z:cllvac80d0000np100qxewqfl#cllvekk1a000bnp100etetexx',
    props: {}
});

sf.ui.logic.mainWindow.groups.whoseDescription.is("Piano Roll").first.groups.whoseDescription.is("Piano Roll").first.sliders.whoseDescription.is("Vertical Zoom").first.children.whoseRole.is("AXValueIndicator").first.mouseClickElement();

I'm not a complete coding noob, but I don't know what to do with this. The Generic Knob Command js just seems to identify me as a 'valid user'. Am I putting code inside the run command? After the run command? Within the props: {} or outside the props: {}? Or am I completely off in how to approach modifying existing script? I initially assumed I could just swap out mouseClickElement() with some equivalent of knobTurnElement(), but I didn't find anything knob-related that I recognized as useful.

Full disclosure, I did try using UI_Element with a macro, and while I could generate access to the appropriate element in the Logic UI, I failed to find anything in the SF codebase that would allow me to convert mouse-sliding into knob turn values. Maybe there's a generic approach to do this, or a function/property I didn't recognize as helpful?

I also gave some thought about reversing the approach, and have the Streamdeck knobs generate MIDI data through SF that could be recognized by Logic using Logic's Learn function. I can get Streamdeck MIDI recognized, but there again, I was stymied by only finding MIDI button and toggle functions, but not an attribute designed to generate 0-126 (1-127) knob values. Did I miss those, or are they not present?

Please advise, and thanks in advance! Cheers.

PS: This is an ai-generated mockup of what I expect I'm in for:

sf.streamDeck.onKnobTurn((event) => {
    const { device, knobIndex, delta } = event;

    // Handle the knob turn
    if (delta > 0) {
        // Knob turned clockwise
        sendMidiCC(device, knobIndex, delta);
    } else {
        // Knob turned counterclockwise
        sendMidiCC(device, knobIndex, delta);
    }
});

function sendMidiCC(device, knobIndex, delta) {
    // Convert delta to MIDI CC value and send it
    const midiCCValue = convertDeltaToCCValue(delta);
    sf.midi.sendCC({
        device: "Your MIDI Device",
        channel: 1,
        cc: knobIndex, // You can map knobIndex to specific CCs
        value: midiCCValue,
    });
}

function convertDeltaToCCValue(delta) {
    // Implement your logic to convert delta to MIDI CC value
    return Math.max(0, Math.min(127, delta));
}
