Disable or control the panel search button?

Hm, quite hacky, but seems to work:

    'hooks' => [
        'route:before' => function ($route, $path, $method) {
            if (Str::startsWith($path, 'api/pages/')) {
                $pagePath = str_replace('+', '/', str_replace('pages/', '', $route->arguments()[0]));
                $page = page($pagePath);
                $user = kirby()->user();
                if ($page && $user) {
                    if ($page->email()->value() !== $user->email()) {
                        throw new Exception('You cannot access this page');
                    }
                }
                
            }
          }
    ]
