Code before:

        formats, subtitles = [], {}
        for media in traverse_obj(media_data, 'medias', default=[]):

            f, subs = self._extract_m3u8_formats_and_subtitles(
                update_url_query(media['url'], {'id_token': self._ID_TOKEN}),
                media_data['id'], 'mp4', m3u8_id='HLS', fatal=False)
            formats.extend(f)
            self._merge_subtitles(subs, target=subtitles)

Review comment (suggestion):
```suggestion
                'location': ('productionCountries', ..., {str}, all, {unpack(join_nonempty, delim='; ')}, filter),
```

and then above, import `join_nonempty` from `utils`, and:
```py
from ..utils.traversal import unpack
```
