<lightning:messageChannel type="lightning__appointmentBooking_greeterDashboard"
                          scope="APPLICATION"
                          onMessage="{!c.onGreeterDashboardMessage}" />

No controlador, manipule a mensagem.

({
    onGreeterDashboardMessage: function(cmp, evt, helper) {
        var eventType = evt.getParam('eventType');
        var eventData = evt.getParam('eventData');

        if (eventType === 'TERRITORY_CHANGE') {
            console.log("Territory changed:", JSON.stringify(eventData));
        }
    }
})
