Why isn't React router dom working in my popup.tsx?

return (
    <>
      <BrowserRouter>
        <Routes>
          <Route path="/" element={<Table data={data} />} />
          <Route path="/similiar" element={<Similiar />} />
        </Routes>
      </BrowserRouter>
    </>
  )

return (
    <>
      <BrowserRouter>
        <Routes>
          <Route path="/" element={<Table data={data} />} />
          <Route path="/similiar" element={<Similiar />} />
        </Routes>
      </BrowserRouter>
    </>
  )
