changed server setting to Oauth2 and lost mailboxes

I could not login this morning with thunderbird. I got this error Login to server imap.googlemail.com failed.. I changed my server setting to OAuth2 and now I can login( I think) and I get inbox listed only with nothing underneath it showing. I lost all my mailboxes. GMAIL login direct is fine.

You have to configure your GMail account to accept "insecure" email client connections and generate an application password for your Thunderbird setup.
