I use the linux Teams App and it crashes if you try to open documents shared in a chat. However the document renders find in the browser. But from the browser we can not use the "call" function. So as a workaround I need to use both which is OK but a bit annoying. I wish the browser would just allow the call function as there is no value added using the app. But if I am forced to use the App then it should work properly. So I decided that I want to file a Bug-Report, but I cant find where the correct place is to do so.
