Describe the bug

A common use case, is to call an api route, after a trpc complete, for example to send an email. API route is usually protected with

// api/emails/notify.ts

const session = await auth()
if(!session){
    return new Response("Unauthorized", {status:401})
}

Because request headers are not available in the trpc procedure, i'm unable to forward them to the fetch call. Is there a better way around it.

USE case

create: protectedProcedure
    .input(CreatePostSchema)
    .mutation(({ ctx, input }) => {
      const v = ctx.db.insert(Post).values(input);
      // WANT TO DO THIS.
      fetch(`/api/emails/notify`, {
           // i would like to forward the user session
     });
     return v;
    }),

Another solution will be to send this into a redis queue, and process these ops later. But that's not the point. I would like to make api calls from trpc procedure. This is just a simplified use case.

just call headers() to get the request headers, if im not mistaken we have that on the context already though?
