 You may want to allow users to send media via your bots inline mode. This works a little bit different than posting media via `send_*`. Most notably, you can't upload files for inline mode! You must provide either an HTTP URL or a `file_id`.

 ## Editing a file
 
-When you have sent a file, you may want to edit it. This works similarly as `send_media_group`, i.e. the media must be wrapped into a `InputMedia<media_type>` object.
