I think you should use the no match route approach.

Check this in the documentation.

https://reactrouter.com/docs/en/v6/getting-started/tutorial#adding-a-no-match-route

import { BrowserRouter, Navigate, Route, Routes } from 'react-router-dom';

<BrowserRouter>
  <Routes>
    <Route path="/" element={<Home />} />
    <Route path="/lab" element={<Lab />} />
    <Route
        path="*"
        element={<Navigate to="/" replace />}
    />
  </Routes>
</BrowserRouter>

To keep the history clean, you should set replace prop. This will avoid extra redirects after the user click back. Thanks @Paul for this tip.
