Best way to generate a report of all users with a specific role with their user name and email?

I'm wanting to generate a report of all users able to raise a PO + their user name/emails. Have figured a good way to do this would be to generate a report of all users with the Buyer role, or Procurement Manager, etc.

I've been able to generate something through the scheduled process "User Role Membership Report", and then filter the generated Excel by users with relevant roles. The issue is that this report only includes usernames and not associated emails.

Is there a better way of getting this data that would also provide user associated emails?

Thanks.
