React and Python in same Intellij project

Right now I have structure like that

this represents the single repo in github

backend is written in Python/Flask, frontend in React

However I am not sure if I configured them correctly in Intellij itself in context of modules projects, facets etc

Ther is little documentaion about how to do this properly

BAckend works fine Intellij autodiscovers stuff there and marks it as Python modules 

the frontend.. not so much
