description: "[TileService] which can consume a Glance composition, convert it to a Wear Tile, and provide it
to the system. You must implement the [Content] function to provide your Tile layout, for
example:
```
class MyTile: GlanceTileService() { @Composable @GlanceComposable override fun Content {   Text(\"Hello World!\") }
}
```

You must also register ComposeTileService instances in your manifest to allow the system to
discover them. Your service must include an intent filter for the action
`androidx.wear.tiles.action.BIND_TILE_PROVIDER`, and require the permission
`com.google.android.wearable.permission.BIND_TILE_PROVIDER`."
