Unable to take control during a Teams session with a Linux Workspace.

Limitations:

• Users on a Linux client cannot Give control to other users. In other words, after the user on the Linux client starts sharing content, the option Give control is not present in the sharing toolbar. This is a Microsoft limitation.
• The Request Control option is not available during the peer-to-peer call between an optimized user and a user on the native Microsoft Teams desktop client that is running on the endpoint. As a workaround (not applicable for the first limitation on Linux), users can join a meeting to get the Request Control option.

Problem Cause

Due MTOP features as MSFT had stopped and fully focusing on the SlimCore Optimization for Linux. Since, this is a feature limitation.
