Hello,
We would like to take advantage of the Group Layer Item functionality that was introduced last year (blog post here) but we're finding that the Experience Builder 'Add Data' widget doesn't appear to recognise them.
A 'Group Layer' item in My Content:

No result when searching for it in the Add Data widget in EB (ArcGIS Online):

I'm assuming this is because 'Group Layers' aren't supported. Is this functionality likely to be added, and if so is there a timeline for it?
Tagging @AlixVezina as I have seen other queries on Group Layers that you have replied to, but nothing for the Add Data widget specifically.
Thanks!
