## Acknowledgements
Some of the skeleton code for setting up the `DreamService` with the
right lifecycle was copied and modified from the [official app's
implementation](https://github.com/jellyfin/jellyfin-androidtv/blob/master/app/src/main/java/org/jellyfin/androidtv/integration/dream/DreamServiceCompat.kt).
