Hi Michael!
Thank you for your continued interest in Teams!
At present, we can make sure this function will be available in Teams for desktop client. But there is no evidence show it will be available in Linux. The best thing we can do is to wait for the end of the week and try to update the Teams for Linux client version to see if it can be also available in Linux. You could also try to update manually by clicking the button “check for update”.
In my test environment, the latest version is 1.3.00.5153.
