How to get accessToken from React context API and put it into Apollo's HttpLink?

I've the following project structure(roughly),

src/
  index.tsx -> entry point for React
  App.tsx 
  client.tsx -> Apollo client definition
  components/
    TokenProvider.tsx -> Provider for accessToken

index.tsx looks like following, it provides apollo-client and the accessToken to whole App.

import React from "react";
import { render } from "react-dom";

import { ApolloProvider } from "@apollo/client";

import { TokenProvider } from "./components/TokenContext";
import client from "./client";
import App from "./App";

render(
  <ApolloProvider client={client}>
    <TokenProvider>
      <App />
    </TokenProvider>
  </ApolloProvider>,
  document.getElementById("root")
);

client.tsx looks like following,

import { ApolloClient, InMemoryCache, HttpLink } from "@apollo/client";

const httpLink = new HttpLink({
  uri: "http://localhost:4000",
  credentials: "include",
});

const client = new ApolloClient({
  cache: new InMemoryCache(),
  link: httpLink,
});

export default client;

I am trying to do some authorization stuff so I need to add authorization header to the HttpLink in client.tsx.

So in index.tsx, I need something like the following,

// in index.tsx

const httpLink = new HttpLink({
  uri: "http://localhost:4000",
  credentials: "include",
  headers: {
    authorization: `bearer ${accessToken}`, // I need this <---
  },
});

The problem is, accessToken variable can be accessed through useContext API, because it is provided by a React Context. But client.tsx is not a React component so I cannot access it.

I set accessToken either in user login or in the beginning of the App if there is refresh token available. So in App.tsx,

// in App.tsx
  useEffect(() => {
    // prevent login in every refresh
    refreshAccessToken().then((accessToken) => {
      // dispatch comes from `TokenProvider`
      dispatch({ type: CHANGE_TOKEN, payload: { accessToken } });
    });
  }, [])

Is there any way to overcome this? Maybe I shouldn't provide accessToken with Context API, what are the other solutions?
