is there a way to update FedEx’s shipment status for testing?

Context

We have FedEx integration on our project. We have a requirement that: shows the delivery status on my order page(not using a Magento OOTB popup with a tracking URL). We will use FedEx API to get delivery status.

Problem

We can create a shipment and retrieve the Tracking Number. The issue on the testing side, the tester wants to test the delivery status change on the UI. With FedEx’s test environment, we don’t know how to update the shipment status(like: pick up, in-transit, delivered). I’m trying to search the API to update the shipment status if any. But no luck yet.

does anyone know how to do that? I am appreciated any comment. Thanks
