 If you would like to run the example that accesses your user data (such as currently playing song etc.), run `pub run example/example_auth.dart`. There, you are requested to
 enter your redirect url (see the comment above [`redirectUri`](#authorization-code-flow)). After that, you are requested to call a given url (or paste it into your browser). That url will do a redirect in your browser. You should copy and paste this redirected url into your console to see the currently playing song and your available devices.
