Delete sent LinkedIn message
Input
threadUrl requiredURL of the conversation thread, e.g. https://www.linkedin.com/messaging/thread/<id>/ (from list_inbox)
match optionalOptional substring of the message text to pick WHICH of your own messages to delete. Defaults to your most recent message in the thread. If several match, the most recent one wins.
Output
status requireddeleted = removed; not_found = no own (non-already-deleted) message matching `match` in the loaded thread; not_deletable = a matching message was found but LinkedIn's per-message menu doesn't offer Delete for it (observed on older messages -- deletion appears to have its own time window, separate from the ~60min edit window)
threadUrl requireddeletedText requiredThe message text that was deleted (null unless status=deleted)
