在我存储为pdf之前,试图更新此文档中所有链接的工作表,我该怎么做?

function convertToPDF() {
  
    var documentId = "1IeY_KXhhdUbPcLIi1WL_nd8AUky5eLDk48Ql1sW6sII"; 
    var document = DocumentApp.openById(documentId); 
    //document
  
    var dynamicId = "12XPDcrng6nZ7ibGziAwNT8eaZ7DYHDoXy3OnknWzyAI"
    let cell = "B13";
    //var sheetName = "sheet1";
    var sheet = SpreadsheetApp.openById(dynamicId);
    var offerName = sheet.getRange(cell).getValue();

    var blob = document.getAs('application/pdf');
    // Set the name of the PDF file
    var pdfFile = DriveApp.createFile(blob).setName(offerName + "_offer" + ".pdf"); 

    var folderName = offerName + "_offer";
    var newFolder = DriveApp.createFolder(folderName);
    pdfFile.moveTo(newFolder);

    

    Logger.log(offerName);
}

在我保存之前,请帮我更新文档中的所有共享表,我在这张表上迷路了。非常感谢
