I’m using C# wrapper.

Now I’m looking for a function to Disable Attendee Annotation,  
but I couldn’t find it.

How can I disable attendee’s annotation??

Hi @HyoSeong,

Thanks for the post. If you would like to disable the attendee annotation, you may use the interface `disableViewerAnnotation`([https://github.com/zoom/zoom-c-sharp-wrapper/blob/1daee9209ce719feb0c8681a497869eed7f86e94/zoom\_sdk\_c\_sharp\_wrap/h/meeting\_service\_components/meeting\_annotation\_interface.h#L158](https://github.com/zoom/zoom-c-sharp-wrapper/blob/1daee9209ce719feb0c8681a497869eed7f86e94/zoom_sdk_c_sharp_wrap/h/meeting_service_components/meeting_annotation_interface.h#L158))

Hope this helps. Thanks!
