Video Dimensions

Meeting SDK Type and Version
Version 2.9.5

Description
We use the Zoom Meeting SDK to embed zoom videos on our website. But we can’t set the correct video dimensions. If we set the customize->video->viewSizes->default parameters, then the video slides out when we share the screen. Can you tell me if this can be fixed?
And the second question, is it possible to hide host windows if screen sharing is enabled?
