Hello all,
I am unable to use Gemini live API in Vertex Studio (in browser). Only getting this for gemini-live-2.5-flash-native-audio and related models. Rest other are working.

getting error:
Some error occurred. Please try again.

Permission ‘aiplatform.endpoints.predict’ denied on resource ‘//aiplatform.googleapis.com/projects//locations/us-central1/publishers/google/models/gemini-live-2.5-flash-native-audio’ (or it may not exist).

I have these APIs in enabled:
Vertex AI API, Cloud text-to-speech API, Gemini for Google cloud API, Generative Language API etc.

I have these roles in my IAM
Owner, AI Platform Admin, Vertex AI Administrator

I am currently in free-tier but have signifcant free tier credits.

Please help, have been stuck on this since a long time.
