        Works for both 1:1 and group chats: a group id is itself a valid typing

        target, so every participant sees the indicator. Best-effort: the

        indicator may be silently dropped if the chat has no recent activity, the

        recipient isn''t on iMessage, or it''s RCS-routed (RCS carries no composing

        state). Auto-expires after a few seconds; no "stop typing" call needed.'
