我正在使用NextAuth登录gitlab，但每2小时我的accessToken就会发生变化，我如何长时间保留它并在数据库中注册。注意：我正在创建一个服务来列出所有客户端存储库。

import NextAuth from 'next-auth/next';
import GitLabProvider from 'next-auth/providers/gitlab';
import axios from 'axios';

export default NextAuth({
  providers: [
    GitLabProvider({
      clientId: process.env.CLIENT_ID,
      clientSecret: process.env.CLIENT_SECRET,
      authorization: { params: { scope: 'api' } },
    }),
  ],
  callbacks: {
    session: async (session, user) => {
      if (!session.accessToken) {
        return session;
      }
      return session;
    },
    jwt: async ({
      token, user, account,
    }) => {
      if (user) {
        token.id = user.id;
      }
      if (account) {
        token.accessToken = account.access_token;
      }
      return token;
    },
  },
  secret: process.env.SECRET,
});
