What happens to attachments during approval process

Summary:

When an approver creates an attachment during the approval process - we could not locate anything on the PR that shows that an attachment was made. They show up when you go back and look at the approvals in your own worklist, but they don't show that any attachments were added on the document history.

Content (required):

Tested this on several PRs, and while attachments showed up for subsequent approvers, once all approvals were complete - there was nothing to indicate to the buyer that additional attachments had been made to the PR - only comments on the attachments showed in Document History and there were not links to the attached documents.
