Gramjs多次登录

如何使用gramjs设置多个会话?文档中没有任何关于多会话的内容。

我已经尝试了以下代码。

import { TelegramClient } from "telegram";
import { StringSession } from "telegram/sessions";
import input from "input"; // npm i input

const apiId = 123456;
const apiHash = "123456abcdfg";
const stringSession = new StringSession(""); // fill this later with the value from session.save()

(async () => {
  console.log("Loading interactive example...");
  const client = new TelegramClient(stringSession, apiId, apiHash, {
    connectionRetries: 5,
  });

  await client.start({
    phoneNumber: async () => await input.text("Please enter your number: "),
    password: async () => await input.text("Please enter your password: "),
    phoneCode: async () =>
      await input.text("Please enter the code you received: "),
    onError: (err) => console.log(err),
  });

  console.log("You should now be connected.");
  console.log(client.session.save()); // Save this string to avoid logging in again

  await client.sendMessage("me", { message: "Hello!" });
})();
