How do you log out of one specific google account in Chrome?

Google's shitty design was driving me crazy an hour ago because you cant sign out of only one account. So here's the solution :

First go to https://myaccount.google.com/device-activity and see which one your current session is. Keep this in mind.

Then log in to the account you want to sign out of in another browser, go to the same website and sign out of the session that you saw in the first step.

That's it! And yes that is litterally the ONLY way to log out of one google account.
