**Description**  
My MacOS desktop app is using a custom UI, calling startWhiteBoardShare to start sharing a whiteboard using the ZoomSDKASController class. When getting an annotation controller (ZoomSDKAnnotationController) via getAnnotationController and calling any subsequent annotation method on it, such as setTool or setColor, I get a ZoomSDKError\_ServiceFailed error. I’ve tried with various tools, colors, and screen types, always erroring out. Any thoughts?

**Which version?**  
I’m using the latest Zoom SDK for MacOS 5.0 release, presumably v5.0.24433.0616 on MacOS Catalina v10.15.7 with Xcode 10.3.

Hi @stalefishlabs,

Thanks for using Zoom SDK and pardon the late response. When using the annotation in Custom UI, please use the interfaces in `ZoomSDKCustomizedAnnotationCtr.h`. The interfaces in `ZoomSDKAnnotationController.h` is for Zoom default UI. Please have a try.

Thanks!

Thanks so much for the reply. I was confused about the roles of the two annotation controllers. That resolves my problem.
