Cannot use 'changeTheme' from PrimeReact Context

I am trying to use the changeTheme functionality as documented here on prime reacts website here

I have setup a very basic online sandbox here

    //CSS
    import "./App.css";
    import { useContext } from "react";
    import { BrowserRouter as Router, Route, Routes } from "react-router-dom";
    import { PrimeReactContext } from "primereact/api";
    import LoginPage from "./components/Loginpage";

    //Prime React styles
    import "primeflex/primeflex.css";
    import "primereact/resources/themes/lara-light-indigo/theme.css";
    import "primereact/resources/primereact.min.css";
    import "primeicons/primeicons.css";

    function App() {
        const {changeTheme} = useContext(PrimeReactContext);
          return (
            <div className="App">
                <Router>
                <Routes>
                    <Route path="/" element={<LoginPage />} />
                </Routes>
              </Router>
           </div>
        );
    }

    export default App;

The line

const {changeTheme} = useContext(PrimeReactContext);

Throws the error Uncaught TypeError: Cannot destructure property 'changeTheme' of 'useContext(...)' as it is undefined.

I have tried reaching out to the authors on their discord as well as searching here and elsewhere online.

You can fix this issues by adding PrimeReactProvider in index.jsx

index.jsx

import { PrimeReactProvider } from "primereact/api";
import { StrictMode } from "react";
import { createRoot } from "react-dom/client";
import App from "./App";

const rootElement = document.getElementById("root");
const root = createRoot(rootElement);

root.render(
  <StrictMode>
    <PrimeReactProvider>
      <App />
    </PrimeReactProvider>
  </StrictMode>,
);

Note: useContext() call in a component is not affected by providers returned from the same component. The corresponding <Context.Provider> needs to be above the component doing the useContext() call.
