Stock does not implement a read function.

To know if the recipient of a message has correctly acknowledged your message, it is more accurate to check whether an active action such as “Got it!” or “Reaction” has been taken.

On the other hand, in situations where the message has only been read, it is not possible to ascertain whether the recipient is accurately confirming the content of the message, as they are often only checking a large number of incoming messages in a primary way.

It is also impractical for the sender of a message to keep track of the messages he or she has sent from a large volume of messages and keep track of the read status of the recipient.

For these reasons, we have decided not to implement the read function as a means of keeping track of the status of messages sent.
