How to import custom sound packs into Moshi app?

[liuxiaotong]

Hi! Love the Moshi app and moshi-hooks integration.

I've created a custom Chinese (zh-CN) sound pack using the OpenPeon format (openpeon.json + mp3 files), with Microsoft Xiaoxiao TTS voice for categories like session.start, task.complete, task.error, and input.required.

My questions:

1. How can I load a custom sound pack into the Moshi iOS app? I see the "Select Sounds" menu in Agent Hooks settings, but it only shows pre-installed packs.
2. Does Moshi pull from the OpenPeon registry? If I publish my pack to openpeon.com, will it eventually appear in the Moshi app's sound selector?
3. Is there a way to import local audio files directly (e.g., via Files app or a URL)?

Would love to contribute a Chinese sound pack to the community. Thanks!
