My company uses the chat system available in Confluence to provide support services to our company's sales agents. The problem I'm facing is that the chat does not make any sounds on the sales agent's side when they get a message. I've tested this myself (see images). Our chat system is integrated with ZenDesk, which is where the chat agents manage the chat tickets.
Is there a setting I'm missing? Where would I look to change it? Or maybe is there an issue with the integration
