          private readonly \SamJUK\FetchPriority\Model\Links\PreloadFactory $preloadFactory
     ) { }

     public function execute()
     {
          // Do Stuff
          $preload = $this->preloadFactory->create([
               'href' => 'https://app.magento2.test/media/my_custom_entity/image1.jpg',
               'mimeType' => \SamJUK\FetchPriority\Enum\Preload\MimeType::ImageJPEG,

          $this->linkStore->add($preload);
     }
}

          private readonly \SamJUK\FetchPriority\Model\LinkStore $linkStore,
          private readonly \SamJUK\FetchPriority\Model\Links\PrefetchFactory $preloadFactory
     ) { }

     public function execute()
     {
          // Do Stuff
