Problem with expired/invalid OAuth2 tokens

My organization uses Google Workspaces/GSuite, and my supervisor needs about forty mailboxes on his laptop (macOS Monterey). These are accessed through POP, with OAuth2 authentication. Previously, when one of these OAuth tokens expired or otherwise became invalid, attempting to check mail on that account would pop up the Google authentication page. Now, it just produces an error message ("The STAT command did not succeed .. Invalid credentials"). In order to re-authenticate to the account, I have to manually go into saved passwords and delete the invalid OAuth token. At that point, attempting to check the mailbox will pop up the authentication page. Is there a way to make it so that, if Google's server replies with "Invalid credentials", Thunderbird will pop up the authentication page automatically, rather than requiring me to manually delete the invalid token? I searched Config Editor, but didn't see anything obvious. Thank you for your time.
