According to this page I should be able to add a CUA here:
Is there an issue with my region (New Zealand) or type of licence that's preventing this feature from being visible?
Thanks everyone!
The feature is available for environments where the region is set to United States.
Since you are in New Zealand you won't see it.
If these suggestions help resolve your issue, Please consider Marking the answer as such and also maybe a like.
Thank you!
Sincerely, Michael Gernaey
