Hi Just installed CI, added a controller, see 404

Hi Guys,
I'm pretty new to CI. Really thanks that we have this forum.
I just installed this version: codeigniter4-framework-v4.4.7-0-ge6a2f70
I use Apache to host web service.
Following instructions, changed AllowOverride to All in Apache configuration.
Changed web document root to "public" folder.
With "localhost" I can call out IG welcoming page.
But as I added an Act "editor":

PHP Code:

namespace App\Controllers;

class Home extends BaseController
{
    public function index(): string
    {
 
        return view('main');
    }
 
 public function editor()
    {
        echo "check";
        //return view('editor');
    }
} 


I call it with:
http://localhost/editor
or
http://localhost/Home/editor
or
http://localhost/index.php/Home/editor
I only see:
404

Sorry! Cannot seem to find the page you were looking for.

I also tried to add another controller:

PHP Code:

namespace App\Controllers;

class Editor extends BaseController
{
    public function index(): string
    {
        return view('welcome_message');
    }
} 


I call it with:
http://localhost/Editor
or
http://localhost/index.php/Editor
I again, see:
404

Sorry! Cannot seem to find the page you were looking for.

I don't read ".htaccess" fluently, anything I can do?
Thank you!

If you are new to CodeIgniter4, try this tutorial:

By default, you need to write routes for the controller method.
See https://codeigniter4.github.io/CodeIgnit...ting-rules

Thank you for the information.
I add a new router:
$routes->get('/Editor', 'Editor::index');

Then I see the new controller!
