Trigger after generative answer provided

Any ideas on how to get a topic to trigger after an initial response from the agent? I want a topic that pushes them to a feedback survey or help reinforce how to write good prompt to get a better answer. Then to the survey if site is still lacking good info. The default path to feedback is to end the conversation by saying a phrase like, 'Bye!', saying 'yes' I got an answer. Not very helpful.
