Shipment with Country of Origin populated at line level using ShipmentTransactionRequest API

When creating Shipments (createAndConfirm Action) through ShipmentTransactionRequest REST API, is it possible to populate the Country of Origin Code at Shipment Line or Line's lot level? When this is not populated, we are seeing the Shipment lines getting stuck in 'Pending inventory processing' line status, the corresponding transaction is stuck as a Pending Transaction in Inventory causing the Shipped line qty not get depleted from Inventory.

Looking for a sample request payload that allows populating Country of Origin during Shipment confirmation using ShipmentTransactionRequest REST API. Or any pointers on any configuration or ESS that resolves the issue explained above.
