Chatbot rasa init conversation

Question

I am starting with rasa and I want to make a chatbot that starts talking before the user, I attach an example:

Bot: Hello, how can I help you?
User: Hello, what time is it?
Bot: It's 5:23 p.m.

I know how to make the user write first but I don’t know how to do it the other way around. I have been looking for information and saw this link: https://forum.rasa.com/t/how-to-let-bot-start-the-conversation/20866/5 but it is still up to the user to write first

I’ve this:

stories.yml:

- story: greet
  steps:
  - action: action_utter_supply_greet_user
  - intention: greet
.... (continues)

actions.py:

class ActionGreetUser(Action):
    def name(self) -> Text:
        return "action_utter_supply_greet_user"
    def run(self, dispatcher: CollectingDispatcher,
            tracker: Tracker,
            domain: Dict[Text, Any]) -> List[Dict[Text, Any]]:
        dispatcher.utter_message("Hello! How can I help you?")
        return[UserUtternanceReverted()]

domain.yml:

actions:
  - action_utter_supply_greet_user

What’s wrong? How can I do it?

Thanks!

Use the /execute rasa endpoint. Or, if you will connect your bot to messaging channel, then try to use those APIs. Example to set up greeting message for Facebook Messenger channel:

from fbmessenger import BaseMessenger
from fbmessenger.thread_settings import GreetingText, GetStartedButton

APP_SECRET = os.environ['APP_SECRET']
PAGE_ACCESS_TOKEN = os.environ['PAGE_ACCESS_TOKEN']

messenger = BaseMessenger(page_access_token=PAGE_ACCESS_TOKEN, app_secret=APP_SECRET)
greeting_text = GreetingText('Hi! how can I help you?')
get_started = GetStartedButton(payload='/get_started')
