Open the Conversations page and click on the client conversation you'd like to send a message about. This will open the Conversation Details screen.
The internal chat section is on the right hand side of the screen on desktop. Simply type your message in the 'team comment' field and click 'send to team', responses will be sent to the same page.
You can also '@message' a specific team member or group when their attention is needed by typing an @ symbol and typing their name (or by selecting from the pop-up). This will send a notification to that user or group.
Note that everyone who looks at this conversation will see the message; it is not private.
