Buffer is not defined error with CRA

The standalone client will throw this error with CRA and package "react-scripts": "^5.0.0":

The reason is that Webpack 5 and CRA v5 don’t add fallbacks for nodejs modules any more.

npm install buffer

window.Buffer = window.Buffer || require("buffer").Buffer;

function App() {
...
}

Personally, I think that the documentation should not state that the package is compatible with browser, if it depends on modules only available on nodeJS. The browser version should include anything necessary to run out of the box, imho.
