Delegated Registration Restart

POST /auth/registration/delegated/restart

Occasionally a user may begin registration but not complete the process. In this case, you can use this method to restart the user's registration where they left off so they can use the same username they originally specified.

On successful creation, the user's registration challenge will be returned. You will then need to call Complete User Registration to complete the user's registration.
