Currently, I have modified three functions to insert Qonversion-related code. Can you help me review whether I have done it correctly?

I have another concern. If, after trying, I am not satisfied with the outcome and decide not to purchase any plan from Qonversion, will the newly added Qonversion-related code affect my app’s performance in production?

Thank you.

    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
        ...
        
        let config = Qonversion.Configuration(projectKey: "XXX", launchMode: .analytics)
        Qonversion.initWithConfig(config)
        
        return true
    }

    private func listenForTransactions() -> Task<Void, Error> {
        return Task.detached {
            //Iterate through any transactions which didn't come from a direct call to `purchase()`.
            for await result in Transaction.updates {
                do {
                    let transaction = try self.checkVerified(result)

                    //Deliver content to the user.
                    await self.updatePurchasedIdentifiers(transaction)

                    //https://documentation.qonversion.io/docs/analytics-mode
                    await QonversionSwift.shared.handleTransaction(transaction)
                    
                    //Always finish a transaction.
                    await transaction.finish()
                } catch {
                    //StoreKit has a receipt it can read but it failed verification. Don't deliver content to the user.
                    error_log(error)
                }
            }
