I am developing this website using python3 backend and react frontend. I tried to set cookies for auth however no matter what setting i try the frontend just does not recognise it, and on refresh the cookie disappears. All the cookie headers work as intended.

Heres my code:
def auth_login(email, password):
match = db.users.find_one({’email’: email, ‘password’: hash(password)})
if match is None:
raise InputError(‘Incorrect email or password’)

session_id, session_end_time = add_login_session(match['_id'])
token = encode_jwt({
    'user_id': str(match["_id"]),
    'session_id': str(session_id),
    'session_end_time': str(session_end_time)
})

# Create a response object
response = make_response({'message': 'Login successful', 'session_end_time': session_end_time})

# Set a cookie on the response object
response.set_cookie(
    key='token',
    value=token,
    httponly=False,  
    secure=False, 
    samesite='Lax', 
    expires=session_end_time,  
    path='/'
)
return response

CORS setting: CORS(app, expose_headers=’Authorization’, supports_credentials=True, resources={r”/*”: {“origins”: “http://localhost:5173”}})

Frontend check:

useEffect(() => {
    const token = Cookies.get('token');
    console.log(token)
    setAuth(!!token);
    if (token) {
        setAuth(true);
        fetchProfileData(setProfileData);
    } else {
        setAuth(false);
    }
}, []);

I even set up a backend endpoint to getCookie, however when that backend is hit also returned nothing. This means that the cookie was never set, or immediately disappeared, However the expiry datetime is 2 hours in the future. very confused.
