Extend FastifyRequest using FastifyPluginAsyncTypebox

💬 Question here

Hey, i'm trying to extend FastifyRequest while using type-provider-typebox.

  let fastify = Fastify(opts).withTypeProvider<TypeBoxTypeProvider>();

  // then in another file
  const route: FastifyPluginAsyncTypebox = async (instance, opts) => {
  instance.register((request, reply) => {
    request.user; // not defined
  });

}
  // maybe the solution is something like this but I'm not sure how:
  // fastify.d.ts
  declare module "fastify" {
    export type FastifyNewRoute = FastifyPluginAsyncTypebox & {
          instance: FastifyInstance... // now sure what to do next
    };
  }
