Making my iPhone a remote because I lost the Apple TV remote
I am trying to pair my iPhone to the Apple TV because I lost the Apple TV remote. But on the remote app on my phone, when I select the tv, it gives me a passcode and says to go to Settings/general/remote to enter the code. But that is in the home screen of the Apple TV and I cannot move around the Apple tv screen to get there because I do not have a remote. How do I get this done so that my iPhone can be my Apple TV remote
iPhone 8, iOS 13
