Fastify request is not accessible in app of next.js 13.

##
I am updating from next.js version 12 to next.js 13. With new App folder sturuture it seems like the fastify request is not accessible in the app. Is there any way we can acess?

```js
fastify.register(require("@fastify/nextjs"), { dev, hostname, port }).after(() => {
server.next("/api/*", { method: "GET" });
server.next("/api/*", { method: "POST" });
server.next("/*", { preHandler }, some-render-logic);
````
