it is not annoying notification, it has a purpose and will prompt if you are in search option in ATV. I have 6 ATV and never touch a stock remote. Always use Siri on my HomePods situated all around the house and use voice command ( spectrum TV) to change the channel without having to scroll via remote app or Stocked remote, but when needing to search something, instead of scrolling through letters via stocked remote, I prefer the notification prompt to type in keywords. By the way with watch OS8 you have remote on your watch automatically appears for you to use it. so I don't need my iPhone remote.
