Adding custom recipient to the emails

Hi Team,

I am having an issue adding a custom recipient which data is from a custom checkout field named: _shipping_email

If I use the basic Woo hooks the recipient is added correctly to the email headers but if I try to use an ID from a custom or third-party added order statuses it’s not working.

Our order statuses:

My code which is working with the completed, processing statuses which are Woo core statuses:

add_filter('woocommerce_email_recipient_customer_completed_order', 'custom_email_recipient_alfiok', 10, 2);

function custom_email_recipient_alfiok($recipient, $order) {

    // Get the shipping email
    $shipping_email = get_post_meta($order->get_id(),'_shipping_email', true);

    // Combine both email addresses if shipping_email exists
    if (!empty($shipping_email)) {
        $recipient .= ',' . $shipping_email;
    }

    return $recipient;
}

But if I try to use filter like:

add_filter('woocommerce_email_recipient_customer_beerkezesre-var_order', 'custom_email_recipient_alfiok', 10, 2);
add_filter('woocommerce_email_recipient_customer_in-transit_order', 'custom_email_recipient_alfiok', 10, 2);

the recipient is not added.

Can you please help me how can I add my custom recipient to the custom order status emails?

Thanks.
Regards,
Peter.
