I have a Google Workspace account with a primary domain business-name.com and an aliased domain for my app app-name.com. I have also created the email alias support@business-name.com and support@app-name.com, both of which point to a single user my.name@business-name.com.
My app, app-name, uses Google OAuth for sign in, but I'd like the consent popup to reference support@app-name.com rather than my personal address at the primary domain.
When I create an additional user in Google Cloud IAM, I can specify support@app-name.com, but the console always resolves this back to my.name@business-name.com and the consent popup always displays the primary user/domain.
If I replace the email alias support with a Group, a similar thing happens; support@app-name.com is published as the primary support@business-name.com
Is there any way to get the Google OAuth consent screen to publish and aliased email address?
