Javascript 如何制作；“后退”；按钮输入'；节点电报机器人api'；？

我有一个机器人，我需要创建“返回”按钮的主菜单。 我尝试使用“bot.onText（//Back/，（msg）），但它不起作用

任务是在一开始我有两个按钮。此外，每个按钮都有分支。我需要在此分支中创建一个“后退”按钮以返回到主bot菜单

我的代码：

require('dotenv').config();
const TelegramBot = require('node-telegram-bot-api');
const bot = new TelegramBot(process.env.API_TOKEN, { polling: true });

const text_amazon = [
   'My text',
   'My text',
   'My text',
   'My text',
   'My text',
   'My text',
   'Back'
 ];
 const text_crypto = [
   'My text',
   'My text',
   'My text',
   'My text',
   'My text',
   'My text',
   'Back'
  ];

 bot.onText(/\/start/, (msg) => {
   chatId = msg.chat.id;
   bot.sendMessage(chatId, 'Hello, ' + msg.from.first_name, {
     reply_markup: {
       resize_keyboard: true,
       // one_time_keyboard: true,
        keyboard: [[text_amazon[0], text_crypto[0]]],
      },
    });
  });


  bot.on('message', (event) => console.log(event.text.toString()))

  bot.on('message', (msg) => {
    // var amazon = text_amazon[0];
    if (msg.text.toString().includes(text_amazon[0])) {
      bot.sendMessage(msg.chat.id, 'Text', {
         reply_markup: {
           resize_keyboard: true,
             keyboard: [
               [text_amazon[1], text_amazon[2], text_amazon[3]],
               [text_amazon[4], text_amazon[5]],
               [text_amazon[6]]
              ],
         },
       });
    }
    if (msg.text.toString().includes(text_crypto[0])) {
      bot.sendMessage(msg.chat.id, 'Text', {
        reply_markup: {
          resize_keyboard: true,
          keyboard: [
            [text_crypto[1], text_crypto[2], text_crypto[3]],
            [text_crypto[4], text_crypto[5]],
            [text_crypto[6]]
          ],
        },
      });
    }
  });
