3D rotation around center instead of 0,0

I’ve created this demo:

as you can see the content rotates around the center

now I’m trying to rotate this the same way:

Clearly the view is registered at 0,0. How do I rotate around the center instead? Here is the code I am using:

        private function loop(e:Event):void {
            
            var distx:Number = mouseX / 1000;
            
            var disty:Number = mouseY / 600;
            
            trace(view.x);
            
            TweenLite.to(view, 1.5, {rotationY: (-6.5+(13*distx)), rotationX: (6.5-(13*disty)), ease:Expo.easeOut});
            
        }

Any help with this would be greatly appreciated.

Thank you,
