Openvidu with python based web app

I have been a basic web app developer but now need to step up my game developing advanced web apps with core technology. I fell in love with openvidu when i was trying to integrate video call in one my django apps which is already in production. i got it installed correctly and working perfectly in the subdomain.
Here is where i got stuck: I need django app to authenticate users in the openvidu call.
Any help will be appreciated.

OpenVidu Call is a demo application with the front-end implemented in Angular and the backend implemented in Node.

It is very easy to re-implement the backend in Python because it is basically a proxy for creating participants tokens.

Take a look to the Node.js code here:
