Storefront API Billing address for order

Shopify Partner
1 0 0

We're currently building a headless Shopify store for a customer using the Storefront API.
When displaying customer's order detail, we would like to show the shipping address as well as the billing address that the order has. I seem to be unable to find a way how to get the billing address out of the Storefront API, is there something I'm missing or is that simply not available?

Thank you,

There is also a duplicate thread
but that has not been answered for over a year..
