I can’t seem to locate my Apple TV app icon on my iPhone homescreen

I can’t seem to locate my Apple TV app on my home screen. Where could it be? It opens when I search for it on the search page. But I can’t see the app icon. When I try to download the app from App Store, it just has the “open” button near it. So it means it’s downloaded, right? But I can’t find the icon anywhere on my home screen.
