Detailed Description

#/components/schemas/Attachment A file, image or link attached to a message.

Attachments are either supplied by the sender, produced by a slash command, or synthesised by the backend when it scrapes a URL found in the message text. Only a handful of fields are meaningful for any given attachment: an image uses ImageUrl, a file uses AssetUrl, and a scraped link fills in the OgScrapeUrl and author fields. Anything not modelled here survives in AdditionalFields.
