How to get orders with used coupon in WooCommerce

Im trying to get orders in WooCommerce (ideally through wc_get_orders) where the coupon code “some_code” was used.

My try:

function get_orders_with_coupon($coupon){
    $customer_orders = wc_get_orders(array(
        'limit' => -1,
        'coupon' => $coupon
    ));
    return $customer_orders;
}

Only one code is used in Woo orders.
