RAG with Atlas Vector Search, LangChain, and OpenAI

Hello @Harshad_Dhavale , I read your blog RAG with Atlas Vector Search, LangChain, and OpenAI | MongoDB
and found it interesting. I am a newbie in this space and learning RAG, mongodb atlas. Is there a github repo for this blog that has all components and working code? I’m now stuck at the last part of your blog that is Gradio component used for generating the application’s web-interface. Would you be able to provide some help? Many thanks
