How to instantiate Model when user is first created using next-auth

[myhendry]

Hi. I need to touch my mongoose model to create a favoriteTweet array when a user is first created by next-auth. If the user already is found inside favoriteTweet then this action will not run again. May i know if this is possible and how can I achieve it?

My [...nextauth].ts file, ...

import NextAuth from "next-auth";
import Providers from "next-auth/providers";

export default NextAuth({
  providers: [
    Providers.GitHub({
      clientId: process.env.GITHUB_ID,
      clientSecret: process.env.GITHUB_SECRET,
    }),
  ],
  callbacks: {
    session: async (session, user) => {
      session.id = user.id;
      return session;
    },
  },
  database: process.env.MONGODB_URI,
});

Thanks
