Chat SDK V2 Memory issue iOS

Hi,

We are using Chat SDK V2 and we see some memory issues. We are presenting the chat as modal and on dismiss we could see instances of `ChatSDK` being retained. The view is getting destroyed properly.

[Strange I am unable to upload any images from the memory graph] so posting some of the contents... as you can see, if I go to the screen around 10 times, you get those many objects retained.

0. ChatSDK(74)

1. ChatEngineStarter (9)

2. ChatFormHandler(9)

3.ZDKChatEngine(9)

4.ZDKChatFormConfiguration(10)

We are building the UI like this 

    func buildUI() throws -> UIViewController {

        // Name for Bot messages

        let messagingConfiguration = MessagingConfiguration()

        messagingConfiguration.name = “Bot"

        let formConfiguration = ChatFormConfiguration(name: .required, email: .required, phoneNumber: .required, department: .required)

        let chatConfiguration = ChatConfiguration()

        chatConfiguration.isAgentAvailabilityEnabled = false

        chatConfiguration.isPreChatFormEnabled = true

        chatConfiguration.chatMenuActions = [.emailTranscript, .endChat]

        chatConfiguration.preChatFormConfiguration = formConfiguration

        

        // Build view controller

        let chatEngine = try ChatEngine.engine()

        return try Messaging.instance.buildUI(engines: [chatEngine], configs: [messagingConfiguration, chatConfiguration])

    }
