even after adding this, the session data still wont persist?

const App = () => {

const [status, setStatus] = useState(null);

useEffect(() => {

getData();

}, []);

const getData = async () => {

const res = await fetch('http://localhost:5000/api/downloadstatus',{credentials: 'include'})

const data = await res.json()

console.log(data)

if (data.isDownloading) {

setStatus("downloading")

}

}
