If you opt to create a custom implementation of the ``MusicDeveloperTokenProvider`` protocol, make sure to discard any cached developer token if the `options` parameter contains ``MusicTokenRequestOptions/ignoreCache``. You can add the newly generated token to an in-memory or persistent cache for faster access upon subsequent requests for this token.
