Customer is using Email2Case, configured to store email attachments as Files (Content Document/Version/Link). They specifically will allow agents to delete these files, as they get many unneeded attachments (logo images, etc). However, they would like to have a record when something is deleted. Is there any way to configure Case Feed (or History Tracking) to record when a linked File is deleted?
If not with config, could I do it in code? I could trigger on delete of the ContentDocumentLink to know the file was removed from the case, but what would I create/insert to show the deletion in the feed?
