When I’m IPTV Smarters and click on the guide to see all the channels in a category, it says “long press menu to add to favorites”….but long pressing menu closes the app!

As I being dense or is there a better/alt way to add a channel favorites in Apple TV??

EDIT: Figured it out. It’s not “long press menu”, but using the Apple remote, you long press the click pad!

I won’t remove it just in case someone else needs this answered!
