A feature is needed that allows the use of a laser pointer during a live stream.

I often watch my friend's game live streams. Sometimes, I want to tell him something, like there's an enemy on his left that he hasn't seen. I can only say it out loud, but usually, it's too late as he has already been killed by the enemy.

So, I'm thinking about providing a feature that allows viewers of the live stream to use a laser pointer on the streamer's screen to more conveniently alert the streamer to any missed information.

To prevent any interference, the streamer should have the ability to allow or disallow the laser pointer at any time.
