如何为“botframwork-webchat”中的每条传入消息添加监听器

import { createMiddleware } from 'botframework-webchat';

function messageListener({ dispatch }) {
  return (next) => (action) => {
    if (action.type === 'DIRECT_LINE/INCOMING_ACTIVITY') {
      const { activity } = action.payload;

      // 在这里添加你的监听器逻辑
      console.log('收到消息:', activity.text);
    }

    return next(action);
  };
}

const middleware = createMiddleware(messageListener);

window.WebChat.renderWebChat(
  {
    directLine: window.WebChat.createDirectLine({ token }),
    store,
    middleware: [middleware] // 将中间件添加到Web Chat中
  },
  document.getElementById('webchat')
);
