Bot owners only, fetch [main mini app preview information, see here »](https://core.telegram.org/api/bots/webapps#main-mini-app-previews) for more info.

Note: technically non-owners may also invoke this method, but it will always behave exactly as [bots.getPreviewMedias](../methods/bots.getPreviewMedias.html), returning only previews for the current language and an empty `lang_codes` array, regardless of the passed `lang_code`, so please only use [bots.getPreviewMedias](../methods/bots.getPreviewMedias.html) if you're not the owner of the `bot`.
