We use GCP Identity Platform to manage multi-tenant authentication with email and password provider.
Google provides a way to configure email templates that are sent when user requests a password reset (in our case, this flow is triggered on the fronted by calling https://firebase.google.com/docs/reference/js/v8/firebase.auth.Auth#sendpasswordresetemail). This will trigger a email send to the user for which identity this method was called. This email, however, is problematic for us: it is sent from the *.firebaseapp.com domain (we want to use our own domain) and since it's been setup initially, it is now not possible to amend body of the email sent or change the "from" email used to send it.
This is how the configuration looks like in GCP console: Identity console
Anyone experienced the same issues or know what is the proper procedure to update email templates?
