    This event is triggered whenever a user is successfully added or edited. if there is any active module in this section on state,
    this module sends a request as a Task tool to the developer call function that includes `user_info()`, `ip()`, `endpoint()`.
    It should be noted; This process does not interfere with the main operation of the system.
    It is just a sender and is active for both side endpoints.
