How about this?

1. Extract zip file with third-party archiver (like "keka").

2. Allow "Input Monitoring".

Excellent advice for me!

I have been able to open the app by your indicated procedure. Thank you very much.

This worked for me.  Had to download the zip with Chrome since Safari automatically unzips.  But using a third-party archiver (Keka) worked for me.  Thanks for the suggestion!
