actions.py

from typing import Any, Text, Dict, List from rasa_sdk import Action, Tracker from rasa_sdk.executor import CollectingDispatcher

class ActionMakeVoiceCall(Action): def name(self) → Text: return “action_make_voice_call”

def run(self, dispatcher: CollectingDispatcher, tracker: Tracker, domain: Dict[Text, Any]) -> List[Dict[Text, Any]]:
    print(tracker.get_latest_entity_values)
    user_entity = next(tracker.get_latest_entity_values("user"), None)
    print("user_entity",user_entity)

    if user_entity:
        dispatcher.utter_message(text=f"Calling {user_entity} now")
