Automatic fullscreen in portal

Hi guys,

I've configured an URL iView in portal, and I want to be automatic fullscreen when I entered this iView(just like I've clicked the FullScreen button), how can get this?

Tips: I've tried the iView parameter "Launch in New Window = Display in Separate Headerless Portal Window(or the other values)", but this will also hide the "Search, New Session, SAP Store, Log off" button, I just wanna exactly same with the FullScreen button -_-

Thank you.
