        // 1. Limit the number of uploaded files
        //    Only to show two recent uploaded files, and old ones will be replaced by the new
        fileList = fileList.slice(-2);

        // 2. read from response and show file link
        fileList = fileList.map(file => {
          if (file.response) {
            // Component will show file.url as link
            file.url = file.response.url;
          }
          return file;
        });
