Announcements or pinned chat?

[MelissaArmo]

I am searching for a way to have an announcement for users when they enter the meeting—something in the chat window.  I have a daily meeting at 9, and we put information in the chat, however, users who come in late will not see the announcement so we have to enter it twice or even move.  Can we leave a banner or a pinned chat at the top so that even latecomers will see the message?
