如何将这个带有回调的链式承诺代码转换为async/await

我不知道如何将这段代码转换为async/await，这样它的可读性就更好了

var responseCallbacks = {};

bot.onText(/\/something/, async (msg) => {
  var callback = responseCallbacks[msg.chat.id];
  if (callback) {
    delete responseCallbacks[msg.chat.id];
    return callback(msg);
  }
  bot.sendMessage(msg.chat.id, "something").then(() => {
    responseCallbacks[msg.chat.id] = (answer) => {
      var something = answer.text;

      bot.sendMessage(msg.chat.id, "something else").then(() => {
        responseCallbacks[msg.chat.id] = (answer) => {
          var somethingElse = answer.text;
          console.log(something, somethingElse);
        };
      });
    };
  });
});
