Hey there @briis, @bdraco, mind taking a look at this pull request as it has been labeled with an integration (unifiprotect) you are listed as a code owner for? Thanks!

Can you add just one platform at a time (either button OR media_player)?

You should really also move the changes to the camera tests to another PR if you can - though I am not sure if you can do so without creating a conflict.

Thanks 👍

While home-assistant/home-assistant.io#20851 LGTM, I'm keeping track of which platforms need to be added since I want to give other reviews a chance to respond before merging.
