How can I get updated file names?

[zanzlender]

I'm updating the file names to be a UUID so I don't get conflicts like so:

const storage = multer.diskStorage({
  // define location where to store
  destination: function (request, file, cb) {
    cb(null, './public/shared');
  },
  // change file name before saving it
  filename: function (request, file, cb) {
    const uniqueName = randomUUID() + '.' + file.mimetype.split('/')[1];
    cb(null, uniqueName);
  },
});

And then in my express routes I define:

const UploadRequest = MulterUploader.array('files');

api.post('/', async (req, res) => {
  UploadRequest(req, res, function (err) {
    if (err instanceof multer.MulterError) {
      console.log('Error while uploading \n -------------------------');
      return res.status(400).send({ code: err.code, message: err.message, name: err.name });
    } else if (err) {
      console.log('Error while uploading \n -------------------------');
      return res.status(400).json({ code: err.code, message: err.message, name: err.name });
    }

    console.log('Successfully uploaded file.');
    return res.status(200).json({
      files: req.files,
      message: 'Upload successful',
      code: 'SUCCESS',
    });
  });
});

Req.files gives the original files w/ filenames Multer received. However, how can I get the newly generated file names created in the DiskStorage filename function?
