TRPC Middleware

How can I create a TRPC middleware function where I can inspect the HTTP headers? I'm in trpc.ts in the server and see the documentation, but I can't piece it all together.

export const activatedMiddleware = t.middleware(async (opts) => {
  const { ctx } = opts;

  return opts.next(opts);

})

export const activatedMiddleware = t.middleware(async (opts) => {
  const { ctx } = opts;

  return opts.next(opts);

})

I have this so far and would like to check the request headers.

Found a solution:

import { type CreateNextContextOptions } from "@trpc/server/adapters/next";

// ...

export const createTRPCContext = (opts: CreateNextContextOptions) => {
  const { req } = opts;

  return {
    ...createInnerTRPCContext({}),
    req,
  };
};

import { type CreateNextContextOptions } from "@trpc/server/adapters/next";

// ...

export const createTRPCContext = (opts: CreateNextContextOptions) => {
  const { req } = opts;

  return {
    ...createInnerTRPCContext({}),
    req,
  };
};
