+## Invisible Panels
+
+To make one or more of your panels an invisible panel, aka hidden from the Extensions menu, make sure to leave the panelDisplayName as an empty string in `cep.config.ts`
+
+```js
+  panels: [
+    {
+      mainPath: "./main/index.html",
+      name: "Invisible Bolt CEP",
+      panelDisplayName: "",
+      ...
+    }
+  ]
+```
+
+You'll want to ensure your panel can be launched from another panel with `csi.requestOpenExtension()` or with an auto-start event in `startOnEvents` in `cep.config.ts` event depending on the app:
+
+```js
+    startOnEvents: [
+      "com.adobe.csxs.events.ApplicationActivate",
+      "com.adobe.csxs.events.ApplicationInitialized",
+      "applicationActivate",
+    ],
+```
