Swap between cameras on Mac App

I just discovered that I can monitor my cameras on my MacBook Pro M1. I can’t figure out how to swap views between the cameras. I know how to do it on my iPhone App but on my MacBook I’m stuck on the view from one of the cameras and can’t figure out how to get to the others.
Thank you

DISCLAIMER: I don’t have an M1 Mac, I’m just speculating here.

How about the back arrow key?

I didn’t see the app show up.

Again I’m guessing, you’ll have to download it from the App Store…

Thank you for your replies. It turns out that just deleting the app and then reloading it worked.
