Sendbird Dashboard Unread Messages (?)

Hi, we are using sendbird_sdk (haven’t migrated to sendbird_chat_sdk) on flutter to implement chatting feature in our application. Our application’s one of main chatting features is customer service and we implemented this using 1 on 1 Group Channel. Our admins reply to the users using Dashboard and there seems to be no means of determining the latest messages sent by the user. So we have to open every channel to check for new messages. Are there any ways to show unread messages or send notification whenever a user sends a message or a way to sort channels by ‘Last message on’ column?

Thank you.
