Bulk uploads with Free Gift Plugin

Hi there, trying to upload bulk coupons that are a free gift, (this plugin here) https://woocommerce.com/products/free-gift-coupons/

Both are the latest versions;

What spreadsheet heading is needed to identify the product for the Free gift? The product ID doesnt work so i assume it needs an extra field somewhere?
