Printing Image from Document Link 1 attribute in ARIS Report

How can i print an image on to a report which is stored in ADS by means of Document Link 1 attribute. In ARIS architect i could easily do this by the following

var document1 = p_aObjOcc[i].ObjDef().Attribute(Constants.AT_DOCUMENTATION, nLocale).getExternalDocument() 

if (document1.isValid()) {

                  

                  if ( document1.getFileExtension().search(/jpg|jpeg|png|gif|emf|tif|tiff/i) != -1 ) {

                      var img = Context.createPicture(document1.getDocument(), Constants.IMAGE_FORMAT_PNG);

                      p_output.OutGraphic(img, -1, 200, 200 )

                  } 

              } 

But unfortunately 'getExternalDocument()' doesnot work in ARIS Connect Designer. Is there any other way i can do this? Appreciate any help.
