React Router v6 の「[PrivateRoute] はコンポーネントではありません」エラーを修正する方法?

import React from 'react';
import { Navigate, Outlet } from 'react-router-dom';

const PrivateRoute = () => {
    const auth = null; // determine if authorized, from context or however you're doing it

    // If authorized, return an outlet that will render child elements
    // If not, return element that will navigate to login page
    return auth ? <Outlet /> : <Navigate to="/login" />;
}

export default PrivateRoute;

<Route exact path='/' element={<PrivateRoute />}>
  <Route exact path='/' element={<Home />} />
</Route>
