Every server DM now says where it came from

Know who DMed you, and why

Join DMs already had a Server Info button. It's now on every DM a server can write itself:

DM	Triggered By
Join DM	Join DM
Moderation invoke (ban, kick, mute, jail, warn…)	e.g. Ban Invoke
Level-up message sent by DM	Level-up Message
Ticket opened, closed or reopened	Ticket Opened / Closed / Reopened
Appeal accepted, rejected or answered	Appeal Accepted / Rejected / Staff Reply

Pressing it shows the server's name and ID, and on a new DM what triggered it.

For server owners

The button is always added and can't be removed, whether your message is plain text, an embed or Components V2. If your message already uses every button slot Discord allows, greed replaces your last button with Server Info. A Server Info button written into your own script is replaced with the real one. See Join DM.
