Teams background on Microsoft 365 / Teams online not available?

[dabesthlm]

I am accessing Teams online via Microsoft 365 portal that opens teams.microsoft.com but when joining a meeting there is no background button available (see the picture attached). Is that not implemented yet?

I am using a workstation with an external camera.

Any input is greatly appreciated

This is the expected behavior afaik, the web client doesnt currently support custom backgrounds.
