Where to view user feedback on answer bot's "was this helpful?"

We are trialing answer bot in our knowledge base and like what we see so far. One of the things we like is that upon answering a query, answer bot asks "Was this helpful?" (see attached). As part of our trial we've been responding to this by clicking on the thumb up or thumb down as appropriate.
What we haven't yet found is where to view the results. We would like to view them -- specifically, the negative feedback -- to help us determine where our knowledge base needs work so that answer bot can be more helpful.
So, where can we review this feedback?
