Samsung SDK TV - Built-in player (sf.service.VideoPlayer) - how to hide its interface?

Question

Samsung

Colleagues,
there is an application for Samsung TV, the built-in player is used and everything is fine, but when the video starts, the player interface is shown on top for a few seconds. Is there an option to turn this off?
Here is the only thing I found - it seems like it's still an HTML page and you can reach the classes, but it doesn't work for me - actually, if the player itself controls the visibility, then I won't interfere with this.
