 *
 * 
 * A card interface displayed in a Google Chat message or Google Workspace
 * Add-on.
 *
 * Cards support a defined layout, interactive UI elements like buttons, and
 * rich media like images. Use cards to present detailed information,
 * gather information from users, and guide users to take a next step.
 *
 * [Card builder](https://addons.gsuite.google.com/uikit/builder)
 *
 * To learn how
 * to build cards, see the following documentation:
 *
 * * For Google Chat apps, see [Design the components of a card or
 *   dialog](https://developers.google.com/workspace/chat/design-components-card-dialog).
 * * For Google Workspace Add-ons, see [Card-based
 * interfaces](https://developers.google.com/apps-script/add-ons/concepts/cards).

   * A card interface displayed in a Google Chat message or Google Workspace
   * Add-on.
   *
   * Cards support a defined layout, interactive UI elements like buttons, and
   * rich media like images. Use cards to present detailed information,
   * gather information from users, and guide users to take a next step.
   *
   * [Card builder](https://addons.gsuite.google.com/uikit/builder)
   *
   * To learn how
   * to build cards, see the following documentation:
   *
   * * For Google Chat apps, see [Design the components of a card or
   *   dialog](https://developers.google.com/workspace/chat/design-components-card-dialog).
   * * For Google Workspace Add-ons, see [Card-based
   * interfaces](https://developers.google.com/apps-script/add-ons/concepts/cards).
