Like it's possible to modify the content of a group I would like to modify the content of a tab using DAML. I tried:
<insertGroup refID="ut_jobmanagement_group" />
But that does not work. The new group won't show up.
The point is: I do not want to modify an existing Esri tab but I want to add a new group to one tab that comes with another of our AddIns. Is that generally possible? Or can I modify Esri Tabs and Groups only?
