Grab graphic layer option by item name

Hello,

I can easily acess a graphic's layer option by using the following:

var doc = app.activeDocument.allGraphics;

doc[0].graphicLayerOptions.graphicLayers.itemByName( "Orange").currentVisibility = true;

Instead of "doc[0]", I would like to grab the graphic by the name/label it has as a item in the layers menu: "Bee".

var test =  app.activeDocument.pageItems.item("Bee");

I get confused, as one is a pageItem and the other a graphic and I'm not good enough in scipting to understand the whole hirachy.

Can someone help?

Thanks alot,

Kosta
