Upgrade to React Router 4 as it brings too many new things and performance improvements.
Links to migrate :- https://github.com/ReactTraining/react-router/blob/master/packages/react-router/docs/guides/migrating.md

since the react version used here is v16.12.0 and we've got React Router 6 already we must upgrade to react router 6 instead of 5, is this still priority:high, if yes I would like to work on this.

Migrating from React Router 3 to React Router 6 may require some significant changes in the code, as there are many breaking API changes between these versions. Some of the main changes are:

• The use of <BrowserRouter> instead of <Router> for web applications.
• The use of <Routes> and <Route> components instead of <Switch> and <Route> for defining routes.
• The use of element prop instead of component or render prop for rendering components in routes.
• The use of useNavigate hook instead of history object for navigation.
• The use of useParams hook instead of match.params for accessing route parameters.

These are some of the major changes that are needed to be made when migrating from React Router 3 to React Router 6.
