We have hooked up a Google Workspace email account to TeamInbox. It has an email like XXX@YYY.com

However we use the alias feature of Google Workspace, so the email we will actually receive emails at and the email we want to send emails from is: XXX@ZZZ.com

TeamInbox tells us that XXX@ZZZ.com is not a verified email and we need to verify it, but it provides no way to do that.

Is there a way to set this up so that XXX@ZZZ.com is a verified and allowed email address even though the login to our Google Workspace account is XXX@YYY.com? It seems like the verify step is just missing from TeamInbox.

Or are Google email aliases just not supported at all?
