The Webex App inside Agent Desktop is controlled through the desktop layout JSON, not merely by installing the Webex App separately. Cisco documentation for supervisor and desktop features points administrators to the webexConfigured setting in the Webex Contact Center desktop layout. The layout also uses the AgentX Webex component identifier to render the embedded Webex application area. That is why the two required parameter combinations are the desktopChatApp object with webexConfigured set to true and the component value agentx-webex. The value webex-app is not the documented component name for this layout object. A generic webexAppEnabled Boolean or webexApp enabled object may look plausible, but it is not the required JSON pattern in the Cisco desktop layout schema. The result is practical: if either the correct component or the webexConfigured flag is absent, the embedded Webex App will not display in Agent Desktop for agent-to-agent, supervisor, or SME collaboration.
