You could use Chromium just for Google Meet. That's what I do. I have Chromium relatively up to date that I basically solely use when I need to. It can be Google Meet, or Teams, or whatever was purposely botched in order NOT to work with Firefox, basically sabotage, but it can also be very rare cases like Lego Spike or GrapheneOS Web installer which require WebUSB.

99.99% I do not need Chromium but when I do, it's worth the ~200MB of used space.
