I have a user myname@mydomain with a GSuite email that I have added as an owner to the firebase project, and I can add that as the project email. However I would like to set help@mydomain as the project email, where help@ is an alias that points to myname@. It is not letting me select this email, and when I tried to add help@ as a user, nothing happened and I cannot see it as a user. Is there a way to do this?
