How can Plasmic with plain React and codegen manage my routes?

I’m trying out plain react with plasmic codegen.
What should I look for for having plasmic generating routes and using screens?
I.e. how can plasmic (codegen) manage my routes?

This page demonstrates how to integrate plasmic with react router catch-all so that it automatically mounts plasmic pages at the correct routes that were specified from plasmic https://docs.plasmic.app/learn/react-quickstart/
