Why am I getting a DataProvider\Document instance in mass deletion?

Question

I am using Magento 2.4 and I want to add a custom admin Grid for company products. The problem is that I get a an error when I want to perform a mass delete action. The problem appears in my action

MassDelete.php

<?php

declare(strict_types=1);

namespace MyDomain\BestSelling\Controller\Adminhtml\Products;

use Exception;
use Magento\Backend\App\Action;
use Magento\Backend\Model\View\Result\Redirect;
use Magento\Catalog\Api\ProductRepositoryInterface;
use Magento\Framework\App\Action\HttpPostActionInterface;
use Magento\Framework\App\ObjectManager;
use Magento\Framework\Controller\ResultFactory;
use Magento\Backend\App\Action\Context;
use Magento\Framework\Exception\LocalizedException;
use Magento\Ui\Component\MassAction\Filter;
use MyDomain\BestSelling\Api\MyProductRepositoryInterface;
use MyDomain\BestSelling\Model\ResourceModel\Products\Grid\CollectionFactory as MyProductsFactory;
Use MyDomain\BestSelling\Model\Products\MyProduct as MyProductModel;
use MyDomain\BestSelling\Model\ResourceModel\Products\MyProduct as MyProductRessource;
use Psr\Log\LoggerInterface;

class MassDelete extends Action implements HttpPostActionInterface
{
    /**
     * @var Filter
     */
    protected $filter;

    /**
     * @var MyProductsFactory
     */
    protected $collectionFactory;
    /**
     * @var MyProductRessource
     */
    private $ressource;

    /**
     * @var MyProductRepositoryInterface
     */
    protected $productRepository;
    /**
     * @var LoggerInterface
     */
    private $logger;

    /**
     * @param Context $context
     * @param Filter $filter
     * @param MyProductsFactory $collectionFactory
     */
    public function __construct(
        Context $context,
        Filter $filter,
        MyProductsFactory $collectionFactory,
        MyProductRessource $ressource,
        LoggerInterface $logger,
        MyProductRepositoryInterface $productRepository
    )
    {
        parent::__construct($context);
        $this->productRepository = $productRepository;
        $this->filter = $filter;
        $this->collectionFactory = $collectionFactory;
        $this->ressource = $ressource;
        $this->logger = $logger;
    }
    /**
     * Execute action
     *
     * @return Redirect
     * @throws LocalizedException|Exception
     */
    public function execute()
    {
        $collection = $this->filter->getCollection($this->collectionFactory->create());
        $collectionSize = $collection->getSize();

        foreach ($collection->getItems() as $product) {
            try {
                $this->productRepository->delete($product);
            } catch (LocalizedException $exception) {
                $this->logger->error($exception->getLogMessage());
            }

            $this->messageManager->addSuccess(__('A total of %1 record(s) have been deleted.', $collectionSize));

            /** @var Redirect $resultRedirect */
            $resultRedirect = $this->resultFactory->create(ResultFactory::TYPE_REDIRECT);
            return $resultRedirect->setPath('*/*/');
        }
    }
}

In the the execute() method I am trying to delete the products with $this->productRepository->delete($product); but then I am getting the error message:

TypeError: Argument 1 passed to MyDomain\BestSelling\Model\Products\MyProductRepository::delete() must be an instance of MyDomain\BestSelling\Api\Data\MyProductInterface, instance of Magento\Framework\View\Element\UiComponent\DataProvider\Document given

Could it be that my Data Provider doesnt provide what I actually need? Here are my configurations:
