Custom Instant Avatar not appearing in v2/avatars API response

Hey everyone! I’ve successfully created and uploaded a custom Instant Avatar via the HeyGen web dashboard, and it's working perfectly there. However, when I call the GET /v2/avatars endpoint, my custom avatar is nowhere to be found in the list—only the stock public avatars are showing up.

I’ve checked my API Key permissions and I'm using the V2 endpoint. Is there a specific filter or a 'private' flag I need to include to see my own creations, or do Instant Avatars require a specific subscription level to be accessible via API? Any help would be appreciated!
