How can I sign out of the GitKraken client?

I'm using a public computer and I can't figure out how I can sign out my account in the desktop client for Ubuntu. I can't find a logout button. My GitKraken account is connected to GitHub, and I need a way to sign out.

For macOS and Unix-like:

rm -rf ~/.gitkraken should do the trick.

I couldn't find any UI to do it otherwise.

Btw it removes all profiles and conf

I just ran into this issue myself and I seem to have found a workaround for it.

Exit GitKraken and go to the AppData folder and delete the GitKraken profile. e.g. Go to C:\Users\yourusername\AppData\Roaming\.gitkraken\ and delete the profiles folder. When you restart GitKraken, you should be signed out and can then sign in to a new account.
