How to detect close button action for default manage subscription in iOS 15?

I have used showManageSubscriptions function show subscription sheet with subscription options within the application but there is a close button in the sheet which action is not detected, button is clickable though.

@available(iOS 15.0.0, *)
    func showManageSubscription(_ windowScene: UIWindowScene) async {
        do {
            try await StoreKit.AppStore.showManageSubscriptions(in: windowScene)
            print("Sheet is closed")
        } catch {
            print("Sheet can not be opened")
        }
    }

Please help me to get the close button action.
