XF 2.1 How to replace usernames in reactions bar with just a number?

[Feanor]

The reactions shown in posts currently include a few usernames. How can I get rid of usernames and replace them with a simple number of how many reactions the post received? (Similar to how Facebook does it.)

This add-on seems to have this functionality unless there's a built in way to do it which I'm not sure as I haven't checked. You might like this add-on though. It basically extends the core reactions and has several bonus features that make it much more worth the experience -> https://xenforo.com/community/resources/content-ratings-for-xf2-1.5600/
