How can I get 'follow-up' suggestion prompts (like OpenWebUI)?

Questions
1

Hi, I’ve only just started working with n8n and AI/LLM. In a short time, I have managed to build a working RAG system and can successfully query the documents in my vector store.
What I’d now like to do is get the system to provide suggested ‘follow-ups’. OpenWebUI does this ‘out of the box’ (see image).

Describe the problem/error/question

So, how can I take the user’s initial input (via chat or webook) and process this to generate ‘Follow-up’ suggestions and append these to the response?

What is the error message (if any)? n/a
