A Microsoft communications service that provides communications capabilities across presence, instant messaging, audio/video calling, and an online meeting experience that includes audio, video, and web conferencing.
At this time the official supported linux distros are debian/redhat. This sound like a feature/application issue and I'm not sure there will be much of a fix for your case.
You can try leaving feedback for the MS Teams team at https://feedbackportal.microsoft.com/feedback/forum/ad198462-1c1c-ec11-b6e7-0022481f8472 but I don't think Ubuntu is supported.
One suggestion is: Is your Microsoft Teams .deb package completely up-to-date or are you running an old version?
Perhaps try running:
sudo dpkg --remove teams and try re-installing the newest package.
