Optional ReadonlyclientThe quoted message's client_context — the mint its own send carried
(replied_to_client_context). A message with no mint keeps the field out
rather than inventing one.
ReadonlyitemThe quoted message's item id (replied_to_item_id).
ReadonlytargetThe quoted message's item_type (replied_to_target_type, e.g. voice_media).
ReadonlyuserThe quoted message's author (replied_to_user_id).
The message a reply quotes: the one whose menu the person replied from. The 451 reply names it in the text broadcast's form (
android-451/direct-message-reply179): its item, itsclient_context, its author and its ownitem_type.
