How do I send a set of youtube URLs from a Mac to the youtube app on Apple TV? On my Macbook I note a series of youtube URLs that I would like to watch, sometime.

They are extended documentaries, and so I'd like to watch them on the TV. The TV is hooked to an Apple TV (4th gen).

I could of course use the youtube app on the Apple TV to search again for the URLs, but this is terribly tedious. It's a task best done on a computer.

Yes, I am aware that I could use AirPlay. But doing so inevitably requires me to run back and forth between the Mac and the Apple TV.

I could also send the URLs via Google Keep to my iPad, and AirPlay from the iPad to the Apple TV, but I'm hoping there is a way that turns the Apple TV into a standalone device, without requiring me to type the URLs by hand.
In your Apple TV YouTube app, you should see an option to activate.. To login to your YouTube account.  Once you follow the instructions displayed on your TV, you should then be logged into your YouTube account and on your TV you can see your favorites and playlists etc.
