Query regarding the flask-auth

I looked into the repo of pycasbin and found flask-auth. I found that really interesting as I have been working on flask framework from last semester and I really faced a lot of difficulty in applying access control. Their is flask-login extension for access control but it is very specific and I don't think it is really helpful in implementing access control for a system with many layers of privileges.
I want to contribute to your organisation this summer. Please guide me through the process

I enjoy coading in python and love to build packages in python which helps in rapid and fast software development.
