Dynamic Icon for Window Open/Close Addon in HabPanel

Hello,

I want to modify the Open/Close Window Addon in HabPanel, so that there is an Icon for OpenState, and an other Icon for Close State.
For now the script is only changing the color of the “window” icon.
Can someone please help me with adding a second icon, so that a can see a “open” window as icon.

<!-- style> img { filter: invert(60%) sepia(100%) hue-rotate(185deg) saturate(1000%) } </style -->
<div 
     
     ng-style="{
      'background-color': itemValue(config.ITEM_ID)=='OPEN' ? config.OPEN_COLOR : config.CLOSED_COLOR
     }"
   >
  <div class="row">
    <div class="ng-binding">{{(config.ITEM_NAME)}}</div>
	</div>
	<div class="row">
    	<widget-icon iconset="'eclipse-smarthome-classic'" icon="(config.ICON)"
     		state=itemValue(config.ITEM_ID) size="(config.icon_size)" center="true" />
  </div>
		<div class="row">
 			<div class="">{{itemValue(config.ITEM_ID)| lowercase}}</div>
		</div>
</div>

Thank you very much,
