Solved: Rasa Submenu with numbers

I’m developing a chatbot for Whatsapp / Signal and microsoft Teams using numbers for navigation and I would like to know what would be the best option to use submenus.

I’ve already managed to use the home menu using rules and duckling.

version: "2.0"
rules:
- rule: Greet Menu Option 1
  steps:
  - intent: informa
    entities:
    - number: "1"
  - action: utter_menu_1

- rule: Greet Menu Option 2
  steps:
  - intent: informa
    entities:
    - number: "2"
  - action: utter_menu_2

Works perfectly, however, when choosing options I would like a new menu with other options, any ideas

I managed using forms with FollowupAction:

rules.yml

- rule: Menu Telefonia
  steps:
  - intent: informa
    entities:
    - number: "13"
  - action: telefonia_form
  - active_loop: telefonia_form
  - active_loop: null

form:

           def submit(
                self,
                #value: Text,
                dispatcher: CollectingDispatcher,
                tracker: Tracker,
                domain: Dict[Text, Any],
            ) -> List[Dict]:
                """Define what the form has to do
                    after all required slots are filled"""
                sender = tracker.sender_id
                telefonia = tracker.get_slot('telefonia')
                if telefonia == '1':
                    #dispatcher.utter_message('Opção - 1')
                    return [FollowupAction("")]
                elif telefonia == '2':
                    #dispatcher.utter_message('Opção - 2')
                    return []
                elif telefonia == '3':
                    #dispatcher.utter_message('Opção - 3')
                    return [FollowupAction("")]
                elif telefonia == '4':
                     #dispatcher.utter_message('Opção - 4')
                    return [FollowupAction("")]
                elif telefonia == '5':
                     #dispatcher.utter_message('Opção - 5')
                    return [FollowupAction("")]
                elif telefonia == '6':
                     #dispatcher.utter_message('Opção - 6')
                    return [FollowupAction("ramal_form")]
                elif telefonia == '7':
                     #dispatcher.utter_message('Opção - 7')
                    return [FollowupAction("")]
                elif telefonia == '8':
                     #dispatcher.utter_message('Opção - 8')
                    return [FollowupAction("")]
                else:
                    return[]
