Logout from Office 365 with Powershell

We got a public computer with windows 10 and the office365-suite in one of our meetings room at my company. On this computer people shall login into their company-accounts, so the office-software is licensed. Some of them don't logout when they leave. They just shutdown the computer. If a next user now starts one of the office programs, the last user will be logged in.

To prevent this, I'm trying to write an powershell script which deleted the cached credentials.

For Microsoft-Teams if found a script which works like a charm.

I already know that Office365 saves the credentials in these registry-keysComputer\HKEY_CURRENT_USER\SOFTWARE\Microsoft\Office\16.0\Common\Identity

But if I start some office-program again the auto-login just needs some more seconds.So I'm asking for some other places, where office365 could cache/save the credentials.
