Feedback nodes ask the user to rate their experience with the assistant and provide any suggestions they may have. This allows you to gather satisfaction metrics and find ways to improve the assistant's performance.
Users can skip providing feedback, but some may also simply close the assistant when they see a request for feedback. Therefore we strongly suggest that you only use feedback nodes immediately before flow end nodes and do not place any other nodes in between.
Additionally, to avoid biasing your metrics we strongly suggest having a feedback node before every flow end regardless of the path the user took to reach it.
