How do I access request meta data in my custom action. I have a rasa application which is running on localhost. I have certain headers within the request that I need to access in my custom action. How to achieve this

Sample Code:

url = “http://localhost:5005/webhooks/rest/webhook

payload = json.dumps({ “sender”: “user”, “message”: “hi” }) headers = { ‘tenantId’: ‘123’, ‘Content-Type’: ‘application/json’ }

How do I access tenantId within my custom action ?
