The draftOrderCreate's shipping line only has title, price, shippingRateHandle: https://shopify.dev/docs/admin-api/graphql/reference/orders/shippinglineinput
In comparison the REST API has those fields AND (https://shopify.dev/docs/admin-api/rest/reference/orders/order#create-2020-10
"carrier_identifier": "third_party_carrier_identifier","requested_fulfillment_service_id": "third_party_fulfillment_service_id"
Does shippingRateHandle of the graphQL API infer these fields? I'm worried that my shipping rates will not be pulled correctly from my fulfillment service when creating draftOrders by API.
