Zoom meeting - Chat

[dgeehot_AR]

I am not sure where to get this question answered. Due to a number of Zoom bombers, when we begin a Zoom session we turn off the chat feature and we advise participants if they have a question to raise their hand. At this .1 of the co-host response back via chat to that individual and asked them how can we help? Since Chat is turned off, as a co-host will be see my message and will they be able to respond back to me while chat is off or do I have to enable chat for the host and co-host in order to communicate.
