Google Hangouts API integration

Hello,

First of all, I’d like to express how thankful I am for discovering Rasa, which is a great platform to build chatbots.

I’d love to use it in my organisation, whose communication solution is Google Workspace. I’m new to chatbot development and I could not gather from the docs at Google Hangouts Chat how to indicate in the Hangout’s API side where to point to my rasa server. Furthermore, I guess there are several different alternatives from both sides to establish pass messages back and forth between Hangouts API and Rasa server, so I’d love some directions where to learn in more detail how to better leverage Hangouts API and Rasa server.

Does anyone know of any tutorial or lost documentation instructing on how to set up the communication between a Google Hangouts chatbot powered by Rasa server?
