title: Custom Message - Laravel 7 - Denied Authorization
body: <p>I have a controller in which in its function it verifies the policy assigned to the Post model :</p>
  <p><strong>App\Http\Controllers\PostController</strong></p>
  <pre><code>class PostController extends Controller
  {
      public function index(Request $request, Post $post) {
          
   $response = Gate::inspect('viewAny', $post);
  
      if ($response-&gt;allowed()) {
          echo 'valid';
      } else {
          echo 'invalid';
      }
      }
  }
  </code></pre>
  <p><strong>File : PostPolicy</strong></p>
  <pre><code> public function viewAny(User $user)
   {
      return $user-&gt;role === 'admin' ? Response::allow() : Response::deny();
   }
  </code></pre>
  <p>when the user is logged in as admin, it returns the message of logged in admin, when it is not admin it returns a 403 response, I would like to replace this 403 response with a message like 'User is not administrator'</p>
