Creating a POC Dust App Using Proprietary API for LLM Integration

Hi! I’d like to create a POC dust APP that would fetch data from proprietary API, render the response into the prompt and feed the LLM with that prompt. I’ve seen that the example for AI search for Zendesk Help Center is doing pretty much the same https://docs.dust.tt/reference/examples Is that example accessible somewhere to replicate some of its behaviour?
