Read receipt is a feature that allows a user to know whether their messages have been read by other users in the channel. The UI for read receipt appears in the MessageList component of
GroupChannelModule. If the sender's message has been read by all recipients in the channel, a colored double-tick icon will appear above the message’s timestamp. Read receipt is only visible to the sender of the message.
