namespace [Vendor]\RecentlyViewed\Block\Customer;

use \Magento\Catalog\Block\Product\Context;
use \Magento\Catalog\Model\Product\Visibility;
use \Magento\Customer\Model\Session as CustomerSession;
use \Magento\Reports\Block\Product\Viewed;
use \Magento\Reports\Model\Product\Index\Factory as IndexFactory;

class RecentlyViewed extends Viewed
{

    /**
     * @var \Magento\Customer\Model\Session
     */
    private $customerSession;


    /**
     * @param \Magento\Customer\Model\Session $customerSession
     * @param \Magento\Catalog\Block\Product\Context $context
     * @param \Magento\Catalog\Model\Product\Visibility $productVisibility
     * @param \Magento\Reports\Model\Product\Index\Factory $indexFactory
     * @param array $data
     */
    public function __construct
    (
        CustomerSession $customerSession,
        Context $context,
        Visibility $productVisibility,
        IndexFactory $indexFactory,
        array $data = [])
    {
        parent::__construct($context, $productVisibility, $indexFactory, $data);
        $this->customerSession = $customerSession;
    }


    /**
     * @return \Magento\Reports\Model\ResourceModel\Product\Index\Collection\AbstractCollection
     */
    public function getRecentlyViewedProducts()
    {
        $collection = $this->getItemsCollection();
        return $collection;
    }

}

Answer 2

Try to use this code. It is useful for current user recent view product display :

protected $recentlyViewed;

public function __construct(
...
    \Magento\Reports\Block\Product\Viewed $recentlyViewed
) {
...
    $this->recentlyViewed = $recentlyViewed;
}

public function getMostRecentlyViewed(){
    return $this->recentlyViewed->getItemsCollection();
    // return recently viewed products for the customer
}
