Add fields to Attachments table

[Arpa_PiemonteGeoportal_Team]

I  need to add some fields to better describe each single attachments (ie "title", "description", acquisition date" etc).

I tryed to add this fields to the attachments table   but no client (agol viewer, editor widget in WAB) seems to recognize these fileds.

Is there a way to customize attachments so they can be edited inside web applications?

ciao

Did you use Desktop (ArcMap or ArcGIS Pro) to add the fields? Did you republish the data to have the changes reflected in the service?

Thank you Xander , I  used ArcMap 10.5 to add fields and to  republish the service.

Shoud i Try with ArcGIS Pro?
