Can we inject property at NextRequest in Next.js

import { DefaultSession } from "next-auth";declare module "next-auth" {  interface Session {    user: {      id: string;    } & DefaultSession["user"];  }}

Like this code, we inject the user object inside next-auth while using this while accessing session.user.idTypeScript does not complain about type.I am using app router and next version is "next": "14.0.4"
