Custom Actions - Variable sender in FormAction

Hello, everyone

I am developing an integration with CRM and need to pass the phone number used in the sender variable, would it be possible to get the value of sender in actions.py?

My code:

def validate_outdoor_seating(
        self,
        value: Text,
        dispatcher: CollectingDispatcher,
        tracker: Tracker,
        domain: Dict[Text, Any],
    ) -> Dict[Text, Any]:
        """Validate outdoor_seating value."""

        if isinstance(value, str):
            if "out" in value:
                # convert "out..." to True
                return {"outdoor_seating": True}
            elif "in" in value:
                # convert "in..." to False
                return {"outdoor_seating": False}
            else:
                dispatcher.utter_template("utter_wrong_outdoor_seating", tracker)
                # validation failed, set slot to None
                return {"outdoor_seating": None}

        else:
             print(value)
            sender = track.sender_id

I got it:

def validate_outdoor_seating(
        self,
        value: Text,
        dispatcher: CollectingDispatcher,
        tracker: Tracker,
        domain: Dict[Text, Any],
    ) -> Dict[Text, Any]:
        """Validate outdoor_seating value."""
        sender = tracker.sender_id # Works now

        if isinstance(value, str):
            if "out" in value:
                # convert "out..." to True
                return {"outdoor_seating": True}
            elif "in" in value:
                # convert "in..." to False
                return {"outdoor_seating": False}
            else:
                dispatcher.utter_template("utter_wrong_outdoor_seating", tracker)
                # validation failed, set slot to None
                return {"outdoor_seating": None}

        else:
        print(sender)
