Use PurchaseAction instead of purchase(options:) for SwiftUI implementations, including multi-scene apps for visionOS. Call the instance to start an in-app purchase.
To use this API, read the PurchaseAction environment value to get an instance of the structure for a given Environment. You call the instance directly because it defines a callAsFunction(_:options:) method that Swift calls when you call the instance.
When you initiate an in-app purchase, the system presents UI for the customer to confirm the purchase details. The purchase action you get from the environment automatically includes the UI context. It presents the confirmation UI in proximity to the scene in which the view displays.
