Custom Matrix emoji to Discord (<img> in formatted_body)

[North-West-Wind]

Some clients (Cinny, FluffyChat) support custom emojis. These emojis are sent as <img data-mx-emoticon> with a mxc:// for src. If a message only contains these custom emojis, the bridge reports that the message is empty.

Will it possible to send this as a custom emoji, or at least send it as a small image (sort of like Freemoji plugin for BetterDiscord)?

This is an example on Cinny:

Source code of message:

  "type": "m.room.message",
