   - Shared presentation payloads: `--presentation` sends semantic blocks (`text`, `context`, `divider`, `buttons`, `select`) that core renders through the selected channel's declared capabilities. See [Message Presentation](/plugins/message-presentation).
   - Generic delivery preferences: `--delivery` accepts delivery hints such as `{ "pin": true }`; `--pin` is shorthand for pinned delivery when the channel supports it.
-  - Telegram only: `--force-document` (send images, GIFs, and videos as documents to avoid Telegram compression)

   - Telegram only: `--thread-id` (forum topic id)
