Code before:
        Deletes the original interaction response message.

        This is a lower level interface to :meth:`InteractionMessage.delete` in case
        you do not want to fetch the message and save an HTTP request.

        Raises
        -------
        HTTPException
            Deleting the message failed.
        NotFound
            The interaction response message does not exist or has already been deleted.
        Forbidden
            Deleted a message that is not yours.

        Parameters
        ----------
        string: Union[:class:`str`, :class:`~discord.app_commands.locale_str`]
            The string to translate.
            :class:`~discord.app_commands.locale_str` can be used to add more context,
            information, or any metadata necessary.
        locale: :class:`Locale`
            The locale to use, this is handy if you want the
            translation for a specific locale.
            Defaults to the user's :attr:`.locale`.
        data: Optional[Any]
            The extraneous data that is being translated.
            if not specified, either :attr:`.command`
            or :attr:`.message` will be passed, depending on which is
            available in the context.
            This can be ``None``.

Review comment (suggestion):
`Optional` is redundant here.
