Need a sound for when a screenshare stops

### Your use case

#### What would you like to do?

Right now when someone stops sharing a screen (like @lampholder), we don't hear any audio identification of it.

#### Why would you like to do it?

Just for parity with our other sounds. Also helps determine when a screenshare has stopped due to a hiccup.

#### How would you like to achieve it?

I need to break out my keyboard again and record something :)

### Have you considered any alternatives?

A visual indication perhaps?
