How can I automatically use react's cache with tRPC on server side?

I have this in my repo:

import { cache } from "react";
import { headers } from "next/headers";

import { createCaller, createTRPCContext } from "@kdx/api";
import { auth } from "@kdx/auth";

/**
 * This wraps the `createTRPCContext` helper and provides the required context for the tRPC API when
 * handling a tRPC call from a React Server Component.
 */
const createContext = cache(async () => {
  const heads = new Headers(headers());
  heads.set("x-trpc-source", "rsc");

  return createTRPCContext({
    auth: await auth(),
    headers: heads,
  });
});

export const api = createCaller(createContext);


But, now I need to understand, how should I export the actual functions from the api caller so they are all cached with react's cache?
I of course could do something like this
export const uglyGetNotifications = cache(api.user.getNotifications);

But I would prefer if I could get an instance of api where all of my endpoints will be using the cache automatically. something like

const notifs = await apiCached.user.getNotifications();
