Magento 2 check if Page is used on more than one website

Question

I'm trying to find if a page is used on more than one website on a multi-website Magento installation.

I have sucessfully return data of the page, but PageInterface has nothing like getStores() or getWebsites().

Here is my code:

public function getPageData($identifier){
        $searchCriteria = $this->_searchCriteriaBuilder->addFilter('identifier', $identifier,'eq')->create();
        $pages = $this->_pageRepositoryInterface->getList($searchCriteria)->getItems();
        return $pages;
    }

Thanks and Greetings!

I found the answer by myself.

In Magento\Cms\Model\Page;There is a method called getStores()

So this is how I made it work:

use Magento\Cms\Model\Page;

use Magento\Framework\View\Element\Template;
use Magento\Cms\Model\Page;

class Main extends Template
{
    protected $_page;

    public function __construct(
        \Magento\Framework\View\Element\Template\Context $context,
        Page $page,

    ) {
        parent::__construct($context);

        $this->_page = $page;
        
    }

    public function getStores(){
        $stores = $this->_page->getStores();
        return $stores;
    }

}
