While setting up the controls for my notification, I'm struggling to understand why `addTargetWithHandler` requires a return type of `Long`, specifically `MPRemoteCommandHandlerStatus`. I’ve tried returning different values, and it seems to work regardless, but I’m unsure about what should actually be returned there. Can anyone explain?

```
val commandCenter = MPRemoteCommandCenter.sharedCommandCenter()
with(commandCenter) {
    pauseCommand.addTargetWithHandler { event ->
        scope.launch {
            pause()
        }
        1
    }
}
```

> Call the addTargetWithHandler: method to add a block to be called. Remove the handler by calling the removeTarget: method, passing in the object returned by this method.
It's just an ID to be able to call the sibling `remove` method
