How to add new value to store using redux hook?

Here is my code

import { createStore, combineReducers } from "redux";
const initalState2 = {
  counter: 0
};

function reducer2(state = initalState2, action) {
  console.log(state, "action");
  switch (action.type) {
    case "INCREMENT":
      return { ...state, counter: state.counter + 1 };
    case "DECREMENT":
      return { ...state, counter: state.counter - 1 };
    default:
      return state;
  }
}

export const store = createStore(combineReducers({ reducer2 }));





import React from "react";
import ReactDOM from "react-dom";
import { store } from "./store";
import { Provider } from "react-redux";
import { ExampleComponent } from "./ExampleComponent";
import "./styles.css";

function App() {
  return (
    <Provider store={store}>
      <div className="App">
        <h1>Hello CodeSandbox</h1>
        <h2>Start editing to see some magic happen!</h2>
        <ExampleComponent />
      </div>
    </Provider>
  );
}

const rootElement = document.getElementById("root");
ReactDOM.render(<App />, rootElement);






import React from "react";
import { useDispatch, useSelector, useStore } from "react-redux";

export function ExampleComponent() {
  const { counter } = useSelector(state => ({
    counter: state.reducer2.counter
  }));
  const store = useStore();
  const dispatch = useDispatch();
  return (
    <div>
      <div>
        <button onClick={() => dispatch({ type: "INCREMENT" })}>INCREMENT</button>
        Counter: {counter}
        <button onClick={() => dispatch({ type: "DECREMENT" })}>-</button>
      </div>
      <button onClick={() => dispatch({ type: "CHECK1" })}>CHeck1</button>
    </div>
  );
}
