Display additonal fields for Attendee

Hi, I am using the Event Ticket Plus with WooCommerce (https://theeventscalendar.com/products/wordpress-event-tickets/).

I am using this code to fetch the attendee meta 
"

add_filter(

    "woe_fetch_order_products",

    function ($products, $order, $labels, $format, $static_vals) {

        $woo_provider = tribe('tickets-plus.commerce.woo');

        $attendees    = $woo_provider->get_attendees_by_id($order->get_id());

        if (!$attendees) return $products;

        $new_products = array();

        foreach ($order->get_items('line_item') as $pos => $item) {

            if (!isset($products[$pos])) continue;

            $added = 0;

            foreach ($attendees as $att) {

                if ($att["product_id"] != $item->get_product_id()) continue;....
$att["attendee_meta"]["name"] = $full_name;"

We have added some addition fields for the attendee to fill in when they purchase the ticket (questions) (https://theeventscalendar.com/knowledgebase/attendee-registration-settings/).

I am not sure how to retrieve those value to display it, and I can't display the total cost for each ticket in the report
