No, I haven't but I'll take a look on that. I prefer using Firefox over
Chrome, but following this:

it's unsupported on making video/audio call - that's not the full truth.
Web behavior depends on User-Agent beeing sent - spoofing it gives the
possibility to make audio call, but that just stopped working in my
case... I can't make audio call neither on Chrome nor on Firefox, so I
suspect it's some MS change.

True, desktop app is the preferred method using Teams, unfortunately
there is no FreeBSD build and I suppose there won't be any... It would
be nice to have it running using our Linux emulation layer - I can help
to test it if anyone is interested.

I'll do my best, Office365 and it's community is still growing
particulary nowadays, in covid-19 times. Many companies use O365
platform, which Teams is a part of.
