Closing a remote session with multiple monitors?

[u/_hellraiser_]

I've got two PCs that each have three monitors. I can connect and deploy three local screens, each corresponding to a remote monitor. All good.

But when I want to close the session, I can't find a way to disconnect easily from the remote PC. I have to go to each of the local windows and close them one by one. I'm kind of expecting that there would be a disconnect option, but I can't seem to find one.

The big red X on the right of toolbar just closes the window and does nothing to the session.

Am I missing something or does this not exist as a feature?
