I want to add the source settings to the Google form auto reply script.

GmailApp.sendEmail(address, title, body, {
  from: 'email address', name: 'sender'
});

 function sendMailGoogleForm(){
  Logger.log('sendMailGoogleForm()debug start');

  //------------------------------------------------------------
  // Configuration Area From Here
  //------------------------------------------------------------

  // Subject, Body, Footer
  var subject="[Acceptance slip]";
  var body
   = This is ●●.\n"
  + "Thank you very much for your recent application.\n"
  + "We look forward to seeing you on the day.\n\n"
  + "\n\n"
  + "----------------------------------------------------------------------\n";
  var footer
  = US>"----------------------------------------------------------------\n"
  + "";

  // Specifying the Input Column Name
  var NAME_COL_NAME = 'Name';
  varMAIL_COL_NAME = 'Mail Address';
  var address="";

  // Mail To
  var admin="event@events.●●.jp";// Administrator (required)
  varcc="; // Cc:
  var bcc = admin; // Bcc:
  var reply=admin;// Reply-To:
  var to = "; // To: (The address of the input person is automatically entered)

  try{
    // Working with Spreadsheets
    varsheet=SpreadsheetApp.getActiveSheet();
    varrows=sheet.getLastRow();
    varcols=sheet.getLastColumn();
    varrg=sheet.getDataRange();
    Logger.log("rows="+rows+"cols="+cols);

    // Email subject/text creation and destination email address acquisition
    for(vari=1;i<=cols;i++){
      varcol_name = rg.getCell(1,i).getValue(); // Column Name
      varcol_value=rg.getCell(rows, i).getValue(); // Input value
      body+="["+col_name+"]\n";
      body+=col_value+"\n\n";
      if(col_name===NAME_COL_NAME){
       body=col_value+"Dear\n\n"+body;
      }
      if(col_name===MAIL_COL_NAME){
       to=col_value;
      }
    }
    body+=footer;
