display subscriptions id on the WooCommerce downloads page-CodePudding

i am completely customizing the woocommerce downloads page, i created a column named subscription in the downloads table and i want to get the id of the subscriptions, i'm a complete beginner and i'm learning, so please don't react negatively to what you think is my simple question, this is the code i wrote, but it doesn't display anything :

path : /themes/theme-name-child/woocommerce/order/order-downloads.php

<?php 
    $order = wc_get_order( $order_id );
    $subscriptions = wcs_get_subscriptions_for_order( $order, array( 'order_type' => 'any' ) );
    foreach ( $subscriptions as $subscription_id => $subscription ) {
?>
    <a href="<?php echo esc_url( $subscription->get_view_order_url() ); ?>"><?php echo esc_html( $subscription->get_order_number() ); ?></a>
<?php } ?>

where is the mistake? please guide me
