Thanks for sharing firejail profile, however doesn't it work in the browser? It is really hidden though, but if you decline 2 times software installation in the Chrome you get a link to join zoom via browser. That's what I had to use a couple of times. The best practice is to avoid installing zoom debian package at all. Btw BBB is also far away from a secure platform imho.
