I can't add my module's Configuration page to admin menu

[TinoArts]

I've generated a basic skeleton from PS module validator, installed it and now I'm trying to put it's configuration page link to the BO side-menu. I've read the documentation, I went through some threads online but I can't find out what I am doing wrong. This is the code:

class MyCustomModule extends Module
{
    protected $config_form = false;

    public function __construct()
    {
        $this->name = 'mycustommodule';
        $this->tab = 'administration';
        $this->version = '1.0.0';
        $this->author = 'John Doe';
        $this->need_instance = 0;
        $this->tabs = array(
            array(
                'name' => 'My custom module',
                'class_name' => 'AdminMyCustomModule',
                'visible' => true,
                'parent_class_name' => 'AdminCatalog',
        ));

        /**
         * Set $this->bootstrap to true if your module is compliant with bootstrap (PrestaShop 1.6)
         */
        $this->bootstrap = true;

        parent::__construct();

        $this->displayName = $this->l('My Custom Module');
        $this->description = $this->l('Lorem ipsum dolor sit amet.');

        $this->ps_versions_compliancy = array('min' => '1.7', 'max' => _PS_VERSION_);
    }
    
    ...
}

 

Of course I've reset the module, even tried uninstalling and installing it again. My new menu tab just doesn't appear.

Thank you.
