/**
 * This example demonstrates adding tracks, removing tracks, and replacing tracks in a playlist. At the time of writing this
 * documentation, this is the available playlist track modification feature in the Spotify Web API.
 *
 * Since authorization is required, this example retrieves an access token using the Authorization Code Grant flow,
 * documented here: https://developer.spotify.com/documentation/general/guides/authorization-guide/#authorization-code-flow
 *
 * Codes are given for a set of scopes. For this example, the scopes are playlist-modify-public.
 * Scopes are documented here:
 * https://developer.spotify.com/documentation/general/guides/scopes/
