如何在react-admin中为自定义路由提供支持？

import React from 'react';
import { Admin, Resource, Route } from 'react-admin';
import { BrowserRouter } from 'react-router-dom';

const CustomRoute = () => (
    <Route
        path="/custom"
        render={() => <div>Custom Route</div>}
    />
);

const App = () => (
    <BrowserRouter>
        <Admin>
            <Resource name="users" />
            <Resource name="posts" />
            <CustomRoute />
        </Admin>
    </BrowserRouter>
);
