问如何获取和使用PDF文件名中使用该脚本导出的单元格的值

EN

function downloadSheetAsPDF2() {
  var ss = SpreadsheetApp.getActiveSpreadsheet();
  var sheetId = ss.getSheetByName("RECEITA PARA IMPRESSÃO").getSheetId();
  var valor = SpreadsheetApp.getActiveSheet().getRange('M3').getValue();  
  var filename = valor;


  // Creat PDF file as a temporary file and create URL for downloading.
  var url = "https://docs.google.com/a/mydomain.org/spreadsheets/d/" + ss.getId() + "/export?exportFormat=pdf&gid=" + sheetId + "&portrait=false&scale=4&access_token=" + ScriptApp.getOAuthToken();
  var blob = UrlFetchApp.fetch(url).getBlob().setName(filename);
  var file = DriveApp.createFile(blob);
  var dlUrl = "https://drive.google.com/uc?export=download&id=" + file.getId();

  // Open a dialog and run Javascript for downloading the file.
  var str = '<script>window.location.href="' + dlUrl + '"</script>';
  var html = HtmlService.createHtmlOutput(str);
  SpreadsheetApp.getUi().showModalDialog(html, "sample");
  file.setTrashed(true);

  // This is used for closing the dialog.
  Utilities.sleep(3000);
  var closeHtml = HtmlService.createHtmlOutput("<script>google.script.host.close()</script>");
  SpreadsheetApp.getUi().showModalDialog(closeHtml, "sample");
}
