Open as linked smart object

Question

Hello,
iam looking for a solution to open files in a folder
and copy then into a document.
Its working good, but i need the files to be linked smart object.
Anyone knows a solution ?
Here my Code so far:
See in line 33. Convert to smart object: ?
var file = new File('C:/User_MY PATH.PSD'),
docRef = open(file);
// Use the path to the application and append the samples folder
var samplesFolder = Folder('C:/USERS_MY FOLDER');
//Get all the files in the folder
var fileList = samplesFolder.getFiles()
  // open each file
  for (var i = 0; i < fileList.length; i++)
  // The fileList is folders and files so open only files
  if (fileList[i]instanceof File)
  open(fileList[i])
  // use the document name for the layer name in the merged document
  var activeDocName = app.activeDocument.name;
  var targetDocName = activeDocName.substring(0, activeDocName.lastIndexOf("."));
  // Copy the Document
  app.activeDocument.selection.selectAll()
  //convertToSmartObject(); THIS ISNT WORKING - CONVERT IT ?
  app.activeDocument.selection.copy()
  // don’t save anything we did
  app.activeDocument.close(SaveOptions.DONOTSAVECHANGES)
  //Select specific layer to paste the copy, this is to make sure the layers are in a specific position
  var doc = app.activeDocument;
  doc.activeLayer = doc.artLayers.getByName("bgr");
  //Paste Document
  app.activeDocument.paste()
  app.activeDocument.activeLayer.name = targetDocName

Use scriptlistener:
var idPlc = charIDToTypeID( "Plc " );
    var desc2 = new ActionDescriptor();
    var idnull = charIDToTypeID( "null" );
    desc2.putPath( idnull, new File( "C:\\Photos\\myPhoto.psd" ) );
    var idLnkd = charIDToTypeID( "Lnkd" );
    desc2.putBoolean( idLnkd, true );
    var idFTcs = charIDToTypeID( "FTcs" );
    var idQCSt = charIDToTypeID( "QCSt" );
    var idQcsa = charIDToTypeID( "Qcsa" );
    desc2.putEnumerated( idFTcs, idQCSt, idQcsa );
    var idOfst = charIDToTypeID( "Ofst" );
        var desc3 = new ActionDescriptor();
        var idHrzn = charIDToTypeID( "Hrzn" );
        var idPxl = charIDToTypeID( "#Pxl" );
        desc3.putUnitDouble( idHrzn, idPxl, 0.000000 );
        var idVrtc = charIDToTypeID( "Vrtc" );
        var idPxl = charIDToTypeID( "#Pxl" );
        desc3.putUnitDouble( idVrtc, idPxl, 0.000000 );
    var idOfst = charIDToTypeID( "Ofst" );
    desc2.putObject( idOfst, idOfst, desc3 );
executeAction( idPlc, desc2, DialogModes.NO );
