Custom Siri Intents and HomePod

Is there any documentation on how Custom Intent's authentication affects executing the intent on HomePod? Right now, if you try to execute an intent on HomePod with "Restricted While Locked" and your iPhone is locked, the HomePod will just ignore it without any feedback. If the paired iPhone is unlocked, the intent will execute. I would expect HomePod to at least provide feedback on why it can't execute the intent.
