How to get shareable file link of downloadable product?

I have a requirement in M2 where I need the shareable file link of downloadable product.

  $product = $this->productRepository->getById($productId);

        // Output array
        $output = [];

        // Get the product downloadable links
        $links = $this->linkRepository->getLinksByProduct($product);
        
        // Add each link data to the output array
        foreach ($links as $item) {
            $output[] = $item->getData();
        }

This piece of code is returning the details with relative path, I want the shareable file link which I can share with others and they can also download, is it possible?
