Dear customer,
Thanks for reaching out to us here in Microsoft Community.
According to your description, you are annoyed about your gmail account constantly asked to login in Outlook. Please correct if I've misunderstood.
For now, Gmail requires user to add OAuth 2.0 to their gmail account on non-google mail apps.
If your account was not configured with OAuth 2.0, Google may think your account can be easily posed to security risk, therefore you may frequently be requested to enter a password to authenticate, and that's the issue you encounter.
Since you are using Microsoft 365 version of Outlook for mac, and you state that your current version of Mac is the latest, you don't have to worry about compatibility.
Generally, you can fix the problem by adding your gmail accounts through an automated process, without having to manually configure them for POP or IMAP. If you have a need to manually sync your gmail with IMAP/POP, you'll need to turn on gmail's double verification and use a one-time specific generated app password.
