Send a message in a conversation

Send a text, image, voice, or file message in a conversation. The client-generated message ID makes exact retries idempotent within the conversation and sender scope. Supports attachments, internal notes (visible only to your org), and reply threads. Updates unread counts and broadcasts to connected WebSocket clients. Labs may also deliver the message to one of the thread's reply endpoints (WhatsApp, SMS, Telegram, Messenger, Instagram or email); it is then queued for delivery.
