Need some tutorials or examples to let dialog agent answer question based on knowledge base.

[LotusPhilip]

I'm working on the RAG multi-agent example. Now I have finished text embedding by importing external pdf files to the knowledge base. Then, I know that another dialog agent is required to get knowledge from the base and answer my question based on such knowledge.

I'm confused that how can I add a dialog agent to get the knowledge and answer my question.
