Need Help with Modules

Hello! I'm trying to add independent modules to my application. I am following the official Guide.

https://codeigniter4.github.io/userguide...dules.html

But seems like I missed something... Cause I am getting a 404 error when I try to access to the Default Home Controller of my Blog Module.

Basically the first thing I did is create a new folder in the Project Root

app/
public/
system/
writable/
modules/
modules/Blog/
modules/Blog/config/
modules/Blog/Controllers/
modules/Blog/Models/...
...
...


Then I create a new namespace for this modules folder in app/Config/Autoload.php

PHP Code:

        $psr4 = [
            'App'         => APPPATH,                // To ensure filters, etc still found,
            APP_NAMESPACE => APPPATH,                // For custom namespace
            'Config'      => APPPATH . 'Config',
            'Modules'     => ROOTPATH . 'Modules'    // MODULES
        ]; 


After that I add that to the Active Explorers (I am not sure what I have to add here... The name of the Namespace? Folder?) app/Config/Modules.php

PHP Code:

    public $activeExplorers = [
        'events',
        'registrars',
        'routes',
        'services',
        'modules'
    ]; 


Next Step is add the Route to the app/Config/Routes.php

PHP Code:

$routes->group('blog', ['namespace' => 'Modules\Blog\Controllers'], function($routes)
{
    $routes->get('/', 'Home::index');
}); 


But I got a 404 when I call this route... (baseURL)/blog

modules/Blog/Controllers/Home.php - I dont know if have to change the namespace inside Blog Controller... But I tried too... and still the same.

PHP Code:

<?php namespace App\Controllers;
// namespace Modules\Blog\Controllers; Not Working Neither

class Home extends BaseController
{
    public function index()
    {
        return view('welcome_message');
    }

    //--------------------------------------------------------------------

} 


Thanks.
