BCC my email for woocommerce compted order

Hi tem :)
Please i need your help, i would like to receive a email copy of customer completed order.

i found that snippet to copy in functions.php theme but seem to make some bug, perhaps have you get a best way ?

+ /**
+ * WooCommerce Extra Feature
+ * ————————–
+ *
+ * Add another email recipient when an order is completed
+ *
+ */
+function woo_extra_email_recipient($recipient, $object) {
+ $recipient = $recipient . ‘, (Email address hidden if logged out) ‘;
+ return $recipient;
+}
+add_filter( ‘woocommerce_email_recipient_customer_completed_order’, ‘woo_extra_email_recipient’, 10, 2);

Thanks
