This feature is available in all editions.
A license is used for any user when an username is stored in the user record. The only exclusions are:
The default admin account that was initially provided when the system was setup
If a member account has been made inactive
Beyond these, every member, regardless of role, consumes a license. If you are bumping up against license limits, or have questions regarding additional license(s) needed, contact Digital.ai Agility Support.
