Backing up AppleTV app to iCloud
So, ever since apple got rid of iTunes, all of my home videos are in the AppleTV app on my mac. I want to back these videos up to iCloud but I can't figure out how to do that. I want them backed up just in case something ever happens to my mac. I would hate to lose all of those precious memories and videos. Does anyone know a solutions to this?
PS- I'm not taking about backing up my actual appleTV device, I'm referring to the appleTV app that replaced iTunes on the iMac PC. I am using iMac 2015 27" model running Monterey v12.6.1 if that helps anyone.
Thank you!
