Hi, I understand what you’re trying to do and it’s definitely possible now on iPad.
Teams recently added the option to share your screen and keep your camera on at the same time.
Here’s how: join your meeting in the Teams app, tap the Share icon and choose Share screen.
Once your screen is being shared, look for the Camera icon in the meeting controls and tap Show my video, this will turn your camera back on so participants can see both your screen and your video feed.
If you don’t see that option, make sure your Teams app is updated to the latest version from the App Store.
Have you already updated the app and checked if the camera icon appears during screen sharing?
Regards,
Aron
