Add Stripe Product ID to Woocommerce Product

Hi, I would like to include Australian gst on my Stripe Receipts. To do so I have created a product on stripe with a price and configured the tax setup. All good so far. Stripe has generated a Product Price API ID to add to the individual Woocommerce product so Woocommerce product and Stripe products are synced and charge the correct price at the checkout. My first question is how can I sync the Stripe product to Woocommerce product. I can’t see anywhere to copy and paste the generated Stripe price API ID onto a single Woocommerce product. Stripe says to change the Woocommerce Product ID number but I can’t see how to do that either as it is preset. Also I have multiple product variations with different prices. Can anyone help please
