I want to alter the User Registration flow to allow for emailing someone when there is a user registration. For altering the flow, this question provides an example.
However, in my case, there is no execution I could add out of the box to email someone other than the user. How can I go on to create a custom execution for sending email in order to send email to admin upon user registration?
Alternatively, I could start continuously polling the list of all users and diff it. This solution using the python-keycloak would be similar to what is described here but for my case, it seems both inefficient and cumbersome, the cron job would have to run all the time. Any other way to solve this problem also welcome!
