How to know which users have the Internal HCM role assigned to them

Summary:

"Internal HCM" is an out-of-the-box user role. Is there a way to generate a report that lists all users with that role? If so, can you provide instructions to do this, as well as indicate what user role has the ability to run this report (i.e., Knowledge Manager)?

We assign knowledge articles to the Internal HCM role quite often, but would like to know which users are actually able to read those articles.
