Configuring OAuth2 for Message Board Mailing Lists

Issue

Basic authentication for emails is no longer available for Gmail, can we use OAuth2 connection with them?
Google Workspace has announced that third-party apps that use only a password to access Google Accounts will no longer be supported, what does that mean for our users?

Since Google has announced the deprecation of less secure apps, using app passwords is the recommended workaround for continuing to use basic authentication with Google accounts for a Liferay Message Board mailing list.
