Users who do not have the 'admin' role when navigating to a closed incident record, they don't have the ability to attach files. They don't see the attachment icon and when they drag and drop a file onto the form, the system throws the following message:
"File attachments not allowed"
This is caused by a Client Script which hides the attachment icon on the form.
