// `message` can be set to `null`. In that case, the timestamp of the latest message (if any) in the conversation or the current time is used as the read timestamp for reporting. If a message needs to be specified, the timestamp of this specified message is used as the read timestamp for reporting. We recommend you use the message JSON content in the message array obtained from the received new message or the message JSON content located by the message locator; otherwise, repeated message JSON content will be constructed.
