如何通过Google App Script打开打印窗口(导出为pdf)？

function printToPDF() {
  var spreadsheet = SpreadsheetApp.getActiveSpreadsheet();
  var sheet = spreadsheet.getActiveSheet();
  
  var url = spreadsheet.getUrl();
  url = url.replace(/edit$/, '');
  
  var exportUrl = url + 'export?exportFormat=pdf&format=pdf' +
      '&size=A4' + // 页面大小
      '&portrait=true' + // 纵向打印
      '&fitw=true' + // 宽度适应页面
      '&sheetnames=false&printtitle=false' + // 不打印标题
      '&pagenumbers=false&gridlines=false' + // 不打印页码和网格线
      '&fzr=false' + // 不打印行标题
      '&gid=' + sheet.getSheetId(); // 导出当前活动表格
      
  var token = ScriptApp.getOAuthToken();
  
  var response = UrlFetchApp.fetch(exportUrl, {
    headers: {
      'Authorization': 'Bearer ' + token
    }
  });
  
  var blob = response.getBlob().setName(sheet.getName() + '.pdf');
  var folder = DriveApp.getFolderById('Folder ID'); // 替换为目标文件夹的ID
  folder.createFile(blob);
}
