def run(self, dispatcher: CollectingDispatcher, tracker: Tracker, domain: Dict[Text, Any]) -> List[Dict[Text, Any]]:
    # Get the user's input for the first slot.
    first_name = input("What is your first name? ")

    # Get the user's input for the second slot.
    last_name = input("What is your last name? ")

    # Do something with the user's inputs.
    print(f"The user's inputs are: {first_name}, {last_name}")

    # Trigger the greet intent.
