How to override a method of flask-security (register_user)?

Hello,

I’m trying without success to override a behavior of Flask-Security: sending confirmation emails. I would like them to be sent to a default e-mail address, whatever the candidate user submitted. So that the administrator can review and filter who’s registering.

It seems the confirmation email is sent by flask.ext.security.registerable.register_user()

def new_register_user(**kwargs):
    # Define a method with new behavior
    ...

import sys

# Override registerable module method
import flask.ext.security.registerable
sys.modules['flask.ext.security.registerable'].register_user = new_register_user
sys.modules['flask.ext.security'].registerable.register_user = new_register_user

# When printing sys.modules, it seems that registerable module
# appears also there:
import flask_security
sys.modules['flask_security.registerable'].register_user = new_register_user
sys.modules['flask_security'].registerable.register_user = new_register_user

Unfortunately, it does not work. The original method is still used. Do you have any hints?

The feature mentioned by @Trii is documented (a little) here: https://flask-security.readthedocs.io/en/latest/customizing.html#emails.
