Hey, I want to use both Github and Discord on my app, and I want to attach the profiles to the sessions so that they are accessible from the client.
The user must first sign in with Discord and then the GitHub account can be linked. Can somebody please explain how I can do this?

import { PrismaAdapter } from "@auth/prisma-adapter";
import {
  getServerSession,
  type DefaultSession,
  type NextAuthOptions,
} from "next-auth";
import { type Adapter } from "next-auth/adapters";
import DiscordProvider from "next-auth/providers/discord";
import GitHubProvider from "next-auth/providers/github";

import { env } from "~/env";
import { db } from "~/server/db";

declare module "next-auth" {
  interface Session extends DefaultSession {
    user: {
      id: string;
      // ...other properties
      // role: UserRole;
    } & DefaultSession["user"];
  }

  // interface User {
  // // ...other properties
  // // role: UserRole;
  // }
}

export const authOptions: NextAuthOptions = {
  callbacks: {
    session: ({ session, user }) => ({
      ...session,
      user: {
        ...session.user,
        id: user.id,
      },
    }),
  },
  adapter: PrismaAdapter(db) as Adapter,
  providers: [
    DiscordProvider({
      clientId: env.DISCORD_CLIENT_ID,
      clientSecret: env.DISCORD_CLIENT_SECRET,
    }),
    GitHubProvider({
      clientId: env.GITHUB_CLIENT_ID,
      clientSecret: env.GITHUB_CLIENT_SECRET,
    }),
  ],
};

export const getServerAuthSession = () => getServerSession(authOptions);
