Accessing request headers in jwt callback in next-auth v5 for non Credentials provider

[Assylkhan]

Is it possible to access request headers in the jwt callback? I used to be able to in v4 the following way (route.ts):

const handler = async (req: NextRequest, res: NextResponse) => {
  const clientIp =
    req.headers.get("x-forwarded-for")?.split(",")[0] ?? "127.0.0.1";
  const userAgent = req.headers.get("user-agent") ?? "Unknown";

  const authOptions = createOptions(clientIp, userAgent);

  return NextAuth(
    req as unknown as NextApiRequest,
    res as unknown as NextApiResponse,
    {
      ...authOptions,
      session: {
        strategy: "jwt",
      },
    }
  );
};

export { handler as GET, handler as POST };

auth.ts:

export const createOptions = (
  clientIp?: string,
  userAgent?: string
): NextAuthConfig => ({
  ...authOptions,
  callbacks: {
    async jwt({ token, account, profile, user, trigger, session }) {

      if (!token.clientIp || !token.userAgent) {
        token.clientIp = clientIp;
        token.userAgent = userAgent;
      }
    ...
    }
  }
}

I.e. so that the same user could log in with different IP and device/browsers. I know that I can access the request from the authorize callback of Credentials provider, but I want to do it for all providers (Google, Twitter, etc.).
However, in the new next-auth v5 NextAuth can be initialized and exported only outside the GET, POST handlers (I can't pass the headers into NextAuth):

export const {
  auth,
  signIn,
  signOut,
} = NextAuth({
  ...authOptions,
  session: {
    strategy: "jwt",
  },
});

Thanks, and sorry if this is a newbie question.
