I am using below code to start annotation using Zoom Meeting SDK for Windows.  
string monitorId1 = Screen.PrimaryScreen.DeviceName.ToString();  
SDKError sDKErrorShScreen = ZOOM\_SDK\_DOTNET\_WRAP.CZoomSDKeDotNetWrap.Instance.GetMeetingServiceWrap().GetMeetingShareController().StartMonitorShare(monitorId1);  
SDKError sDKErrorStAn= ZOOM\_SDK\_DOTNET\_WRAP.CZoomSDKeDotNetWrap.Instance.GetMeetingServiceWrap().GetAnnotationController().StartAnnotation(SDKViewType.SDK\_FIRST\_VIEW);

StartMonitorShare returns SDKERR\_SUCCESS.  
StartAnnotation returns 15.  
Please provide the solution.
