Is there a github repo for gemini OpenAI compatibility sdk?

Hello, I would like to know is there a github repo for the gemini OpenAI compatibility sdk? For javascript particularly.

I want to checkout the source code for the response object mapping between the native google sdk vs the openai sdk after some discussion from a different topic (question-with-usage-in-openai-compatibility).

I was searching thru GitHub - googleapis/js-genai: TypeScript/JavaScript SDK for Gemini and Vertex AI. but cannot find anything openai related.

The closest thing I found was GitHub - google-gemini/proxy-to-gemini: A proxy sidecar to access Gemini models via OpenAI and Ollama APIs but I believe that is deprecated.
