Copy Paste Session Names From Document

Hello! I'm a new SoundFlow user and I love it. One of the scripts I'm working on involves building a lot of sessions from a template using information given to us by our client in Google Sheets. Eventually I'll figure out a system that's intelligent enough to "read" the Google Sheet and do things automatically for me, but for now I'm using keyboard press to navigate around the Google Sheet and copy information into Pro Tools.

The issue I'm having is when I try to copy the name I want into the Save Copy In dialogue. I get an Apple error message when the script goes from focusing on Safari to focusing back on Pro Tools. Command + V is not available for some reason when this happens nor is Edit > Paste from the dropdown menu, but right-click > Paste in the name field are available. Whenever I do either of those, however, for some reason it selects the whole text previously entered and pastes over it. Not sure why? I'm happy with how the script works up to this point. Here's what I have for that part of the script:

//back to Pro Tools
sf.ui.proTools.appActivateMainWindow();

sf.wait({
    intervalMs: 2000,
});

sf.ui.proTools.windows.whoseTitle.is("Save").first.textFields.whoseValue.is("CM_1610_pvLC_").first.popupMenuSelect({
    isRightClick: true,
    menuPath: ['Paste'],
});

sf.wait({
    intervalMs: 200,
});

//add underscore
sf.keyboard.type({
    text: "_",
});

//back to Google Sheets
sf.ui.app('com.apple.Safari').appActivateMainWindow();

sf.wait({
    intervalMs: 200,
});

//move to cue name
sf.keyboard.press({
    keys: "right",
});

sf.keyboard.press({
    keys: "cmd+c",
});

//back to Pro Tools
sf.ui.proTools.appActivateMainWindow();

sf.wait({
    intervalMs: 2000,
});

//paste cue name
sf.ui.proTools.windows.whoseTitle.is("Save").first.textFields.whoseValue.is("CM_1610_pvLC_").first.popupMenuSelect({
    isRightClick: true,
    menuPath: ['Paste'],
});

//add session name suffix to save copy in
//sf.keyboard.type({
    text: "_v1_PREP",
});
