We’ll also display a temporary popup using a Notification to let our users know their feedback has been submitted.

Edit your submit_button_click function to look like this:

def submit_button_click(self, **event_args):
  name = self.name_box.text
  email = self.email_box.text
  feedback = self.feedback_box.text
  anvil.server.call('add_feedback', name, email, feedback)
  # Show a popup that says 'Feedback submitted!'
  Notification("Feedback submitted!").show()
