How to use the xdl.Logger.global function in xdl

let notificationOptions = {
            indefinite: !!chunk.indefinite,
          };

          if (chunk.level <= bunyan.INFO) {
            this._showNotification('info', chunk.msg, notificationOptions);

          }
        },
      },
      type: 'raw',
    });

    Logger.global.addStream({
      stream: {
        write: chunk => {
          this._appendLogChunk(chunk);
        },
      },
      type: 'raw',
    });
