Zoom Video SDK Virtual background with imagetype is not working

Zoom Video SDK Virtual background with image type is not working:

*I am using Video SDK integration in iOS mobile app, I integrated Virtual background functionality using zoomcml framework, in this Virtual background with blur is working and virtual background with image is not working, Even though when we retreiving list of virtual background it is not giving ZoomVideoSDKVirtualBackgroundDataType_Image type, Does anyone aware about it , Even I tried adding addVirtualBackgroundItem method to add an image but still not working
