## Overview

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