+# LiveCollaborationTrigger
+
+If you implement live collaboration support and want to expose the same UI button as on [excalidraw.com](https://excalidraw.com), you can render the `<LiveCollaborationTrigger/>` component using the [renderTopRightUI](/docs/@excalidraw/excalidraw/api/props#rendertoprightui) prop.
+
+You'll need to supply `onSelect()` to handle opening of your collaboration dialog, but the button will display `appState.collaborators` count provided you have supplied it.
+
+| Prop | Type | Required | Default | Description |
+| --- | --- | --- | --- | --- |
+| `onSelect` | `function` | Yes |  | Handler called when the user clicks on the button |
+| `isCollaborating` | `boolean` | Yes | false | Whether live collaboration session is in effect. Modifies button style. |
+
+```tsx live
+function App() {
+  const [excalidrawAPI, setExcalidrawAPI] = useState(null);
+  const [isCollaborating, setIsCollaborating] = useState(false);
+  return (
+    <div style={{ height: "500px" }}>
+      <p style={{ fontSize: "16px" }}>
