Does ChatGoogleGenerativeAI support tuned gemini model?

[BarryC7]

I follow the fine-tuning tutorial with my data, like "tunedModels/xxxxxxx", I can load this tuned model with genai.GenerativeModel, but I cannot load it with ChatGoogleGenerativeAI, so how can I load the tuned Gemini model by langchain. Do I have to use Vertex AI?
