This is a small lesson that covers a tiny feature of RTK Query that enables two additional refetch options: refetchOnMount and refetchOnReconnect.

In order to support them you need to include setupListeners() in your redux store. And then you'll have the ability to automatically refetch data when your page comes into focus or reconnects to the network. The main idea is if you're outside of the page on a different app and come back it will make sure your users are seeing the most up-to-date information.
