redux toolkit에서는 redux thunk가 들어있는건가요?

import { configureStore } from "@reduxjs/toolkit";
import { createWrapper } from "next-redux-wrapper";
import reducer from "../reducers";


function getServerState() {
  return typeof document !== "undefined"
    ? JSON.parse(document.querySelector("#__NEXT_DATA__").textContent)?.props
        .pageProps.initialState
    : undefined;
}

const serverState = getServerState();
console.log("serverState", serverState);
const makeStore = () => {
  configureStore({
    reducer,
    devTools: true,
    middleware: (getDefaultMiddleware) =>
      getDefaultMiddleware(),
    preloadedState: serverState, // SSR
  });
};

export default createWrapper(makeStore);

https://redux-toolkit.js.org/api/getDefaultMiddleware
이걸 읽어보니

configureStore에서 middleware의getDefaultMiddleware()에 redux thunk가 이미 추가가 되어있는거 같은데 맞나요?
