title: Hook into form submit of Elementor pro form widget
body: <p>I have created a form with the Elementor form widget and it should be a user registration form.
  Now I want to get the form input fields and add the user to the database.
  How can I get the form fields? And the sending of the e-mail (which the Elementor form widget does by default) has to be cancelled. I can cancel it via <code>exit</code> after the execution of my custom code (insert user to db) so that the Elementor ajax call doesn't send the e-mail.<br />
  There are some hooks in the widget (f.e. &quot;<code>elementor_pro/forms/form_submitted</code>&quot; and some others) but I would like to know the appropriate way to do this.</p>
  <p>Do you have some idea? Please let me know.</p>
  <p>Thanks a lot!</p>
