How to get "movie set artwork automator" add-on in OSCM

I don’t see the add-on listed in the default Kodi repositories “Kodi add-on repository” or “popcornmix add-ons”.

Is it supported in Kodi 16.1 on OSCM?

Will it work with Aeon Nox 5 Redux, Confluence or OSCM default skins?

You should be trying to find out who the developer of the addon is and how you can contact and ask them. We have no idea what the addon is or if it would work in OSMC or any other skin.
