Open participant and chat like popup window instead of a panel inside zoom container

Meeting SDK Windows

@carson.zoom And @Michael_Condon

So I’m trying to get the chatDialog window handle but It’s been proving a bit difficult. I have been doing it in the following manner after the meeting window has opened successfully
I’m doing it in the following manner

IMeetingUIControllerDotNetWrap uictrl_service = CZoomSDKeDotNetWrap.Instance.GetMeetingServiceWrap().GetUIController();
    ShowChatDlgParam firstHwd = new ShowChatDlgParam();
    ValueType va_1 = firstHwd; 

    uictrl_service.ShowChatDlg(ref va_1);
    ShowChatDlgParam chat_exposed = (ShowChatDlgParam)va_1;

the Code below is causing problems because of the casting of a null

HWNDDotNet temp = (HWNDDotNet)chat_exposed.hChatWnd;
Console.WriteLine("Chat window handle " + temp.value);

The output I get before the crash is the following

Object reference not set to an instance of an object.

I’m trying to follow the findings from this post

The Question

How do I get the handle of the Chat window?
