Communicating with Group Chat
Group chat is a public form of chat; you can use it to send typed messages to everyone in the meeting. If group chat is available in the meeting, you can use group chat when audio is unavailable or when you need to ask a question during a meeting and do not want to interrupt the person who is currently speaking. Although everyone in the meeting can see the group chat message, only participants with permission to chat can send a message.
