Refunding non-consumable in-app purchase made in TestFlight

Hey everyone, I'm aware that subscriptions purchased via TestFlight expire more quickly according to schedule dictated by the sandbox environment.

But what about non-consumables? Can non-consumable purchases via TestFlight be refunded in any way?

I've been looking around and can't find that information.
