 * Defines a template for displaying message attachments.
 *
 * To define an attachment template, nest an `<ng-template>` tag with the `kendoChatAttachmentTemplate` attribute inside the `<kendo-chat>` component.
 * The template context is set to the attachment instance.
 * For more information, refer to the article on [message attachments](https://www.telerik.com/kendo-angular-ui/components/conversational-ui/chat/attachments).
 *
 * You can use the following field:
 * - `attachment`&mdash;The attachment instance.
 * - `message`&mdash;The message instance.
 *
 * @example
 * ```html
 * <kendo-chat>
 *   <ng-template kendoChatAttachmentTemplate let-attachment let-message>
 *     <div>Attachment: {{ attachment.content }}</div>
 *   </ng-template>
 * </kendo-chat>
 * ```
