Not getting to the right page in React Router Dom?

Question

Frontend

Good evening gentlemen.
There is a React site that uses react-router-dom.
Let's say a person went there, went to other pages and copied the url of the page and threw it off to someone, and the url was something like this mysite.com/contacts . When a person types this url, he gets 404.
To open the page (that is, the contacts component), the user needs to go to it from the main page. How to make it possible to immediately open the desired page (Component).
(I apologize for the bad explanation, I don't know Russian well)))

Answer 2

Go to the APP, there look for the contacts component, or something that renders contacts, a container for example - write something like
Something like this, if I correctly understood the essence of the problem.
