A: In menu / audio video settings, you can change virtual backgrounds during a meeting.

Also, We have a free app we’re about to release that does a much better job on most systems. It’s coded and we’re just waiting for the code signing certificate.

In the meantime time, Macs have background replacement built into the OS (click the purple icon on the menu bar) and if you have an nvidia rtx, you should be using “nvidia broadcast”.

The other possible option is vcam by xsplit but that costs a few dollars a month.
