help with setting up routes rules

Hi,

I am having trouble in setting up the routing rules. In the app/Config/Routes.php, all HTTP verb use would result with 404, but get. Here's how I am setting up the rules which is in trouble.

PHP Code:

$routes->group('admin', ['namespace' => 'App\Controllers\Admin'], function ($routes) {
    $routes->add('/', 'User::index');
    
    $routes->group('page', ['namespace' => 'App\Controllers\Admin'], function ($routes) {
        $routes->add('/', 'Page::index');
    });
}); 


But this works.

PHP Code:

$routes->group('admin', ['namespace' => 'App\Controllers\Admin'], function ($routes) {
    $routes->get('/', 'User::index');
    
    $routes->group('page', ['namespace' => 'App\Controllers\Admin'], function ($routes) {
        $routes->get('/', 'Page::index');
    });
}); 


Thank you for your time in advance.
