email sending need to authorized as [email protected]

[andiechu]

Status

Now everyone who wants to send onboarding email need to set [email protected] in their own Gmail account (howto: https://docs.google.com/presentation/d/18rz5NO1eWUwYhTQuD9nU_VP6KYEhpa-sriTALRUAPxg/edit).

Requirements

As an account manager, I don't want to set up the email in my own panel. I want the authorization bounded to the document/script, so that every time I run the script, I was run the script as [email protected]
