Greetings, I followed the tutorial "Create a Generative Chat App with Vertex AI", where my data store consists of one large text file. This text file essentially is a collection of my documentation (live on a website) but stored in one file. However, I want to be able to provide realtime links to the actual website if needed. How canI best format my document to also provide these links that users can click when interacting with the chat app? Any suggestions?
