As the host, you can control who meeting or webinar participants are allowed to chat with. You can also disable the chat for all participants or disable private chat, so participants cannot send private messages.

Controlling Chat Access
Meeting and webinar hosts can control whether participants can chat with everyone, with panelists and the host (for webinars), or only with the host.
Disabling In-Meeting Chat
You can turn chat for all of your meetings and webinars from your Profile Settings, if you do not want to use the chat in your meetings and webinars. This will prevent the host, co-hosts, and participants from chatting for any meetings you host. The Chat option will no longer appear in the Meeting Controls.
You can disable the Private Chat, which will prevent participants from sending messages to individuals instead of the entire group.
