I need to return the intent confidence in action. How could it possibly be done?

class ActionHelloWorld(Action):

def name(self) -> Text:
    return "action_hello_world"

def run(self, dispatcher: CollectingDispatcher,
        tracker: Tracker,
        domain: Dict[Text, Any]) -> List[Dict[Text, Any]]:

    # how to get confidence
    confidence = 0

    dispatcher.utter_message(json_message=
        {
            "confidence": confidence,
            "text": "Hello World"
        }
    )

    return []

Hi @aroma. Why do you want to return confidence in an action?
