    """Link to a file stored on the Telegram servers.

    By default, this file will be sent by the user with an optional caption.
    Alternatively, you can use input_message_content to send a message with the specified content instead of the file.

    Parameters:
        title (``str``):
            Title for the result.

        file_id (``str``):
            Pass a file_id as string to send a media that exists on the Telegram servers.

        id (``str``, *optional*):
            Unique identifier for this result, 1-64 bytes.
            Defaults to a randomly generated UUID4.

        description (``str``, *optional*):
            Short description of the result.

        caption (``str``, *optional*):
            Caption of the document to be sent, 0-1024 characters.

        parse_mode (``str``, *optional*):
            By default, texts are parsed using both Markdown and HTML styles.
            You can combine both syntaxes together.
            Pass "markdown" or "md" to enable Markdown-style parsing only.
            Pass "html" to enable HTML-style parsing only.
            Pass None to completely disable style parsing.
        caption_entities (List of :obj:`~pyrogram.types.MessageEntity`):
                List of special entities that appear in the caption, which can be specified instead of *parse_mode*.

        reply_markup (:obj:`~pyrogram.types.InlineKeyboardMarkup`, *optional*):
            Inline keyboard attached to the message.

        input_message_content (:obj:`~pyrogram.types.InputMessageContent`):
            Content of the message to be sent.
