[scripting] How to detect if the Smart Filters mask is selected?

[Signfeld]

I could not detect this by checking for a Layer name of 'Smart Filters'.

How can I detect if the Smart Filters mask is active/selected, please?

From https://community.adobe.com/t5/photoshop/smart-filter/td-p/10758108?page=1 I've tried this snippet but it alerts "false" whether I'm on or off the mask ...

sTT = stringIDToTypeID; (ref = new ActionReference()).putProperty(sTT('property'), iI = sTT('itemIndex'))

ref.putEnumerated(sTT('channel'), sTT('ordinal'), sTT('targetEnum')), alert(!(executeActionGet(ref).getInteger(iI) > 3))

Thanks!
