Snippet: Auto-Delete Past Event Invite Links

Auto-Delete Past Event Invite Links
eagleclarinet22 — eagleclarinet22
Will auto-delete event-specific invite links after event has passed (uses scheduledevents.retrieve to test if event ID is valid and deletes if not). Note: will only work for the latest 50 messages and will only work if the Discord event-specific invite link is the only thing in the message content.
