Warning - Latest Zoom update won't work on older Macs

The latest Zoom update announced today with AI is for "silicon" Macs.  Older Macs won't accept it. I did the download and install and it replaced my previous version of Zoom.... when I went to open it I received a message that it won't work on my 2019 Powerbook Pro (it is not a "silicon" Mac).  Fortunately I had the previous version of Zoom on a backup and could re-install it.  There is nothing in the email from Zoom warning users about this.  A problem!
