 *
 * @link https://core.telegram.org/bots/api#inputmediadocument
 *
 * @property string $type Type of the result, must be document.
 * @property string $media File to send. Pass a file_id to send a file that exists on the Telegram servers (recommended), pass an HTTP URL for Telegram to get a file from the Internet, or pass “attach://<file_attach_name>” to upload a new one using multipart/form-data under <file_attach_name> name.
 * @property InputFile|string|null $thumb (Optional). Thumbnail of the file sent. The thumbnail should be in JPEG format and less than 200 kB in size. A thumbnail‘s width and height should not exceed 90. Ignored if the file is not uploaded using multipart/form-data. Thumbnails can’t be reused and can be only uploaded as a new file, so you can pass “attach://<file_attach_name>” if the thumbnail was uploaded using multipart/form-data under <file_attach_name>
 * @property string|null $caption (Optional). Caption of the document to be sent, 0-200 characters
 * @property string|null $parseMode (Optional). Send Markdown or HTML, if you want Telegram apps to show bold, italic, fixed-width text or inline URLs in the media caption.
