No itunes store account
Trying to download apps on my Apple tv. When I click download it has me put my password in. I do, then it reads an error message saying , no itunes store account. Before using this Apple ID on your Apple tv, you must first login into an IOS device, Mac, or PC to create an itunes store account. The Apple tv is the only Apple electronic I own. How do I go about this?
Apple TV 4K, tvOS 15
