Convert latest file in google spreadsheets-CodePudding

I need some help, I have the script below that converts a ".xls" file into google spreadsheet, but I need you to always use the most recent file that is in folder A, I can't do that.

function importXLS(){
  var folderBId = "ID FOLDER"; // Added // Please set the folder ID of "FolderB".
  
  
  var files = DriveApp.getFolderById('ID FOLDER').searchFiles('title != "nothing"');
  while(files.hasNext()){
    var xFile = files.next();
    var name = xFile.getName();
    if (name.indexOf('.xls')>-1){ 
      var ID = xFile.getId();
      var xBlob = xFile.getBlob();
      var newFile = {
        title : 'backlog' '_converted',
        parents: [{id: folderBId}] //  Added
      };
      file = Drive.Files.insert(newFile, xBlob, {
        convert: true
      });
    }
  }
}

Most recently updated file in a folder

function mostrecentlyupdatedfileinafolder() {
  const folder = DriveApp.getFolderById(gobj.globals.testfolderid);
  const files = folder.getFiles();
  const fa = [];
  while(files.hasNext()) {
    let file = files.next();
    fa.push(file);
  }
  fa.sort((a,b) => {
    return b.getLastUpdated().valueOf() - a.getLastUpdated().valueOf();
  });
  //let fnA = fa.map(f => f.getName()).flat();
  //Logger.log(JSON.stringify(fnA));
  return fa[0];
}
