editMessageMedia method

Future<Message> editMessageMedia({ dynamic chat_id, int? message_id, String? inline_message_id, InputMedia? media, String? parse_mode, InlineKeyboardMarkup? reply_markup, })

Use this method to edit audio, document, photo, or video messages

If a message is a part of a message album, then it can be edited only to a photo or a video. Otherwise, message type can be changed arbitrarily. When inline message is edited, file can't be uploaded. Use previously uploaded file via its file_id or specify a URL.

On success, if the edited message was sent by the bot, the edited Message is returned, otherwise True is returned.
