Elastic audio type selector no longer working

@Kitch awhile back you helped me with an awesome script to set Elastic Audio to whatever setting I wanted on selected tracks. The script is no longer working. I just updated my ProTools, maybe that's the issue? The error prompt that pops up says the issue is on Line 5?

System info:
M2 Mac OS 14.5
ProTools 2024.10
SF v.5.9.0

Here is the script:

function setElasticAudioPlugin({ plugin }) {
    const track = sf.ui.proTools.selectedTrack;
    const elasticAudioOrAraPlugInSelector = track.popupButtons.whoseTitle.is("Elastic Audio or ARA Plug-in selector").first

    elasticAudioOrAraPlugInSelector.popupMenuSelect({
        menuPath: [plugin],
        isOption: true,
        isShift: true,
    });
}

sf.ui.proTools.appActivateMainWindow();

setElasticAudioPlugin({
    plugin: 'Monophonic'
});
