Checkouts API, Orders & gift_card usage

historically we have queried Checkout - REST checkouts.gift_cards.amount_used via the admin rest api to determine for a given historical order how much of the purchase amount was paid for via gift cards.

However, the Checkouts API is being deprecated (Deprecation of Checkout APIs — Shopify developer changelog). According to the Cart API Migration Guide we should migrate to use the Storefront Carts API. However, that API deletes completed carts (Migrate to the Storefront Cart API)
“Completed carts are deleted upon order creation. Unlike the Checkout API, you can’t query a completed cart …”

So, now that the Checkouts API is deprecated is there another way to query gift_card usage for a given order id (ideally through the Admin Orders API)?
