List of related products IDs

Hi, i need to get list of related IDs in content-single-product template, it is possible? Something like that:

<?php

$product_id = get_the_ID();

$related_product_ids = wc_get_related_products($product_id);

foreach ($related_product_ids as $related_product_id) {
echo $related_product_id;
}; 

?>

Thank you
