Add agents under Agents: a name, a title or department, a WhatsApp number and an optional photo. When at least one agent is active, the floating button opens a panel where visitors choose who to message.
Tick Set working hours on an agent to enter a schedule for each day. Outside those hours the agent is shown as offline with the next opening time, for example “Offline · Back tomorrow at 09:00”. With Hide offline agents they disappear from the panel instead. Overnight shifts such as 22:00–02:00 are supported.
Working hours use the time zone in Settings → General. Make sure it is set to your city.
