How to configure redux-persist with redux-toolkit?

store.js

import {configureStore} from '@reduxjs/toolkit';
import storage from 'redux-persist/lib/storage'
import {combineReducers} from "redux"; 
import { persistReducer } from 'redux-persist'
import thunk from 'redux-thunk'

const reducers = combineReducers({
 //...            
});

const persistConfig = {
    key: 'root',
    storage
};

const persistedReducer = persistReducer(persistConfig, reducers);


const store = configureStore({
    reducer: persistedReducer,
    devTools: process.env.NODE_ENV !== 'production',
    middleware: [thunk]
});

export default store;

Index/App.js

import store from './app/store';
import { PersistGate } from 'redux-persist/integration/react'
import { persistStore } from 'redux-persist'

let persistor = persistStore(store);

    <Provider store={store}>
        <PersistGate loading={null} persistor={persistor}>
        <App/>
        </PersistGate>
    </Provider>,
