我想用handle.php将所有404错误重定向到主页，我用的是laravel 8，请帮助我。

<?php

namespace App\Exceptions;

use Illuminate\Foundation\Exceptions\Handler as ExceptionHandler;
use Symfony\Component\HttpKernel\Exception\NotFoundHttpException;

use Throwable;

class Handler extends ExceptionHandler
    /**
     * Register the exception handling callbacks for the application.
     *
     * @return void
     */
    public function register()
    {
        $this->renderable(function (NotFoundHttpException $e, $request) {
          
        });
    }
