Laravel - Implicit route model binding with soft deleted data

//Route Service Provider
 $router->bind('post', function($post)
     return Post::withTrashed()->where('id', $post)->firstOrFail();
});

// Controller
public function show(Post $post) {

// If the post has been trashed and the user is not admin, he cannot see it
     if (!Auth::user()->isAdmin() && $post->trashed())
         abort(404);

     // Proceed with normal request because the post has not been deleted.
}

Route::get('posts/{post}', [PostController::class, 'show'])->withTrashed();
