enable Offline Playback
Allows the player to use locally saved media files for playback.
This method enables playback of media items that are saved locally without requiring a DRM license. Before using this method, ensure that a valid Token/OTP and Playback Info are provided using setToken and setPlaybackInfo. However, it is generally recommended to use setOfflinePlayback for offline playback, which should be handled with enqueueV2 for downloading media items.
