Turn off Waiting Room Pop-up Message!

When you have the waiting room enabled, and there are people in the waiting room, you will get a pop-up on the bottom right of the screen.  It tells you there are # people entered the waiting room. It has a button to view.  

We want the waiting room but with 10 or so co-hosts managing a large Zoom with multiple breakout rooms. we hate the pop-up on the bottom right that tells us there are people in the waiting room. We know they are there. That pop-up gets in the way of us answering the chat!

It is so annoying and I don't see a way to turn it off.   Attached is a screenshot of the notification that we desperately want to turn off!
