Zoom with Wayland - Fails on starting a session

I am using Ubuntu 21.10 and have been having difficulties getting a Zoom session going. It was crashing each time I started a session, I found it necessary to restart Zoom usually 3, 4 or 5 times before it got going, once started it would stay working.

Ubuntu 21.10 uses a Snap install of the Zoom client

$ snap list zoom-client
Name         Version     Rev  Tracking       Publisher  Notes
zoom-client  5.9.1.1380  167  latest/stable  ogra       -

In the log file: ~/snap/zoom-client/current/.zoom/logs/zoom_stdout_stderr.log

I found entries that pointed to Zoom not being happy running with Wayland

Prior to version 21.10 Ubuntu's login screen had a button bottom right that gave you the option to select XOrg or Wayland, that has gone now so I needed a different way to select XOrg in preference to Wayland. I followed the instruction at:

[https://askubuntu.com/questions/1380829/no-option-to-choose-x11-on-logging-into-ubuntu-21-10][1]

This worked and the Zoom client now starts OK

Does anybody know how where to put this information and thus prompt a fix to make the zoom-client work with Wayland ?
