Plex: resume playback by media_content_id

Want to create script to switch Android TV to another application, then contuinue playback in Plex.

Before switching see media_content_id & media_content_type as attributes of media_player.
BUT, then can’t (or don’t know) resume playback by that information.

By using saved variables and code

                media_content_type: '{{ tv_hall_media_type }}'
                media_content_id: '{{ tv_hall_media_id }}'

Plex starts playback from episode/movie beginning.

To specify resume afaik id/type is not enough, need to supply library_name etc. etc.

Would be nice to have simple way to continue playback som far known media_content_type & media_content_id.
