How to find live view

Hi, I have a battery powered doorbell. I found the live view a few times when setting things up, but I can’t find it now.

Can anyone tell me where to find this please?

When you start the app it should default to “devices” and show the view from the doorbell camera the last time it was activated. There’s a large “play” button in the centre of the picture (the usual triangular icon) - touch that to play the live view.
