Additional team and channel-related features and issues within Microsoft Teams for Education
Hello #SistaB,
The feature to give control other participants is still available in Microsoft Teams. Please see the instructions below.
The first time you share your screen or documents in Teams, you will see a sharing toolbar at the top of the screen like the screenshot below:
But the toolbar will be hidden automatically in a few seconds. You can put the mouse at the top of the screenshot, and it will display now. Click Give control button and select the name of the participant you want to give control to.
Moreover, the participants can also click Request control button on their side. Once it is approved by the presenter, they will also be able to take control.
For more details about this feature, please see Give and take control of shared content part in this article: Share content in a meeting in Teams
Regards,
Rick
