How to get download link from a order in Woo-commerce?

I am trying to get download link of a product in Order data. But i am getting error.

Below is my code:

$order = new WC_Order( 206956 );

foreach ( $order->get_items() as $item_id => $item ) {

    echo $product_id = $item->get_product_id(); // product ID

    $downloads = $item->get_item_downloads();
    print_r ( $downloads );

}

I tried this solution also.

$order->get_item_downloads();

Thanks
