CodeIgniter 4 - How to autoload Database library?

Hello,
Please help me what should I write (and in which file) to automatically load the database library. Now I try to do it like this and it works:
Thank you!

Controllers/Test.php

PHP Code:

<?php

namespace App\Controllers;

class Test extends BaseController
{
    public function index(): string
    {
        $db = \Config\Database::connect();

        $query = $db->query('SELECT name FROM users');
        $data['results'] = $query->getResult();

        $data['title'] = 'Title';
        $data['description'] = 'Description';
        
        return view('test', $data);
    }
} 


You can also do this.

A convenience method exists that is purely a wrapper around the above line and is provided for your convenience:

PHP Code:

$db = db_connect(); 


What did you Try? What did you Get? What did you Expect?

I'm answering myself, maybe this will be useful to someone.

Initiate the Database globally on the BaseController in the "initController" function:

PHP Code:

$this->db = \Config\Database::connect();

// And use it anywhere:

$query = $this->db->query('SELECT name FROM users');
$data['results'] = $query->getResult();
