Row level security for Power BI embeding

Hi All,

I have implemented the Power BI embedded using the developer's samples provided by Microsoft on it's github. The embedding is done for customers with python Flask web application. The app is authenticated with MasterUser.

Now, I want to proceed with Row level security in the embedded application. So how should I proceed with it?

I have assigned the required roles in Power BI desktop and have tested it as well. Further I have assigned respective users to those roles in Power BI service.  

So I need a little guidance on how to implement rls for embedding in python web application.
