Can't find a route for 'post: login' after customizing login and register routes

Can't find a route for 'post: login'

Post method is not working in Login

I want to use CI Shield Post:login route but it does not display in route list.
Have to make custom login route for Post?
What I do? I want to customize default login view.

$routes->get('login', 'AuthCtrlr::loginView');
$routes->get('register', 'AuthCtrlr::registerView');
service('auth')->routes($routes, ['except' => ['login', 'register']]);
// service('auth')->routes($routes);
