NOTE:
I already asked this question and it was closed because it is supposedly a duplicate of this one. I made an edit explaining the difference but it was never revised. The difference with that post is that it explains how to add a NEW email. But that answer is useless if you want to use an alias of the same email. The reason is that when the alias is entered in IAM, it detects it as the primary mail.
Then there's this related question, but it's 9 years old and I can't find any of the sections mentioned in the answer. Probably changed the interface.
Question
The "user support email" field in Google Oauth Consent does not allow me to enter an alias.
Initially, it shows me only my email (name@company.com).
I can add any other email in the IAM section successfully, except if the email is an alias. If the email is an alias (eg: support@company.com), when I add the new user in IAM it detects it as the primary email.
How can I use my G Workspace email alias on the consent screen?
