I've been fighting with a problem for the last couple of days (I'm new to M2), so I hope you can help me further in this task to find a solution. I've been following this guide: https://www.mageplaza.com/magento-2-module-development/create-admin-grid-magento-2.html

My controller (Index.php)
class Index extends \Magento\Backend\App\Action
{
protected $resultPageFactory = false;
public function __construct(
\Magento\Backend\App\Action\Context $context,
\Magento\Framework\View\Result\PageFactory $resultPageFactory
) {
parent::__construct($context);
$this->resultPageFactory = $resultPageFactory;

$resultPage->getConfig()->getTitle()->prepend((__('Labels')));
return $resultPage;

The result is just a blank page with the title "Labels". It doesn't add any grid to the page? Do you have any idea where the problem could be? I hope you guys can help me with this.
