how could I get ai_coustics works?
I only get the error from livekit.plugins.ai_coustics of: “Unable to authorize model use: Model use unauthorized”
seems there are a feature gate check, but we are on paid account

I’m running self-hosted agent but from doc / demo it should just work

Can you share your agent logs for where this happens?
