Hi i have integrate my chat-bot with hangout. Now i want to extract the user email id for creating the ticket. I have found the documenation as shown in the linkhttps://github.com/RasaHQ/rasa/blob/main/rasa/core/channels/hangouts.py#L209. But i dont know how to use the extract function. SO any help will be greatly appriciated.
I am able to do now. i just need to modify the extract_sender function.
Glad to know you solved it on your own 
It would be great if you could share your code for future readers and mark it as solution
