Video is disabled while sharing screen on calling apps like Zoom, Teams, Meet

While sharing the screen in any video call app, like Zoom, Teams or Meet, the video is disabling automatically.

This is what i do:

• Open meeting link in any calling app
• click on screen sharing
• ”Ok” on screen broadcasting popup
• Now the screen is sharing, my video is disabled, still I can see the other participants video, the video icon in the calling app is disabled.
• When i try to enable my video on clicking the video button app, a pop up is showing, “You can’t use your camera while sharing your screen”
