Can I get a beep when my game has a full table and is ready to start?

It can take a long time for a table to fill up. I’m not going to stare at it the whole time. Is there a way I can register, and then when the table is finally full it will beep so I know it’s time to play? I feel like it’s an obvious feature, but I can’t find it. Thanks.

I get the white box, but no beep. At least I know it exists, thanks. Just have to figure out how to turn it on.
