Hello,  
I’m trying to set up a sing up workflow. Unfortunately the documentation didn’t help as it is outdated and the trigger “On submit” if missing. However I get the following error message. Any idea what could cause this error?

message: “Email address cannot be used as it is not authorized”

cause

\_\_isAuthError: true

name: “AuthApiError”

status: 400

code: “email\_address\_not\_authorized”

You need to either set up your own SMTP or use the address that you used to sign up into Supabase. This is so that people dont abuse the free emails they provide.
