Screen Share suggestion

Hi! I was thinking about it for like a week, then i said to me why not making a suggestion.
So, when you are with someone in a group or DM in a call, someone started to screen share and maybe you're playing a game, and the screen share is lagging you, then you say to the person if he can turn off his screen share, but he refused and saying he don't want to turn it off. At the moment, you are mad because you have a low PC and you can't play because of his screen share. But what about you can turn his screen share off, and keep playing? And when your game is done, you can turn it on again!
