# messenger_delivery_apply

Send one text message from you to a direct or basic group room of the Messenger app (pApp D00003), as the room message input does. Requires change {text, confirmation SEND_CHAT_MESSAGE}; the text stays within the room's limit. The preview leads with the recipient count; a changed count refuses the send. A sent message cannot be recalled (hiding is done on the console). When sending cannot run here, the answer is MESSAGING_DELIVERY_CONSOLE with the room on the console (consoleUrl), and nothing is sent. The preview never sends. A lost receipt stays pending and is never resent; task_resume only observes, and prepared work needs the identical apply. Called without confirmToken it previews and returns a confirmToken; repeating the same input with it executes once.
