🔴please help me after step 06:23:07 64. React Rendered by Django , when I update reactjs and go to localhost:8000 I don't see any changes.!!!

Note, I'm musing react with tsx (typescript)
my index.tsx file

import React from "react";
import ReactDOM from "react-dom";
import "./index.css";
import App from "./App";
import reportWebVitals from "./reportWebVitals";
const getelem = document.getElementById("root");
getelem && ReactDOM.render(<App />, getelem);

reportWebVitals();

my templaes/react.html file has the same code that i copied from build/index
and I did all the other steps.
see my repo
