From the UI, where can we view the group categories

[kimhuang]

Here is the scenario, the group category is created with the course by csv.

---

group_category_id,account_id,course_id,category_name,status

AMS399-HIS399_F2019_GC02,,AMS399-HIS399_F2019,Precepts,active

---

When the course was deleted, I thought the group_category would be deleted with the course, but actually, it was not.  The group_category exists independently and globally. When the course is deleted, the group_category still exists.

How do I view or delete group_category(group set) if needed?

Thank you so much,
