Change focus app in Apple TV
I have an Apple TV 4K and Apple TV HD as well. When I reset my Apple TVs (both of them), after the Apple TVs restart and go through all the initial settings (language, region, etc...) and come to the Home screen, the focus app is automatically Apple TV+ in 4K and Movies in HD.
By 'focus app', I mean the selection place of the remote stops at that app, and for Apple TV 4K, the upper banner of the screen will show the images of that app (as photo below)
Is it possible for me to change it to another one (other than Apple TV+ or Movies)?
For example, I myself developed an app for Apple TV, and I want to make it as the focus app.
Many thanks!
