Does react router allow you to create a public component with its own routing?

Question

JavaScript

I'm trying to use the useRouteMatch hook to create a component with my own routing
https://reacttraining.com//web/guides/quick-start section "Nesting" and as a result I get a
TypeError: useContext(...) is undefined
I'm like this I understand reacr-router requires one context for the entire application and not for a separate component
