How to setup ineractive-endpoint in RASA

Question

I am trying to deploy RASA chatbot on slack but I am facing an issue as shown in the picture below:

I am unable to understand what URL is it asking for. In rasa endpoints.yml I have only action_endpoint as below :-

action_endpoint:
url: "http://localhost:5055/webhook"

Now slack is not picking up the url. So, please help me with what url I have to put here and where is that URL ?

I am new to RASA and Stack Overflow, so apologies if the question is low level.

Any help on this is appreciated
Thanks

You need to expose your local rasa server (not the action server) running at localhost:5005 using ngrok, then fill that spot with the URL of this type http://<host>:<port>/webhooks/slack/webhook as indicated in the docs.
