## Overview

`CometChatCollaborativeDocumentBubble` renders a collaborative document card — a banner image, a title, a subtitle, and an "Open Document" button. It is **self-extracting**: pass the SDK `message` and the bubble reads the document URL from the message's extension metadata (`@injected.extensions.document.document_url`), so it works standalone. Clicking the button opens the document (by default in a new window).

<Note>
  **Requires the Collaborative Document extension enabled in the [CometChat Dashboard](/fundamentals/collaborative-document).** Document messages (`extension_document`) — and the injected `document_url` this bubble reads — are only produced once the extension is turned on for your app. Without it the composer cannot create documents and this bubble never renders. See the [Collaborative Document guide](/fundamentals/collaborative-document) to enable it, and the [Plugins overview](/ui-kit/react/plugins/overview#built-in-plugins) for how the UI Kit auto-routes document messages to this bubble.
