Remotely logging out of Apple TV on a Smart TV?

I have a rental property that I inadvertantly left my AppleTV app account logged in on 2 SmartTVs making it available to renters to use. I need to have it signed out and I can't figure out how to remotely log out of the session. I am able to do this with Netflix and AmazonPrime with no trouble.

AppleTV has been far more of a mystery and I can't figure it out. Help would be appreciated.
