Why subscription screen doesn't open if the Subscription is not active? Xcode Swift iOS

I have used showManageSubscriptions function to show the subscription sheet with subscription options within the application but when a subscription is not purchased or not active the sheet is not open.

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

Is there any way to open the sheet in this case even subscription is not purchased or not active? So users can at least buy again.

I want Apple's default subscription sheet like this to buy a subscription.
