script .osb for maya 2019

Good morning, I have the permanent Hamrony 15 version but I can’t find a way to download scritp to export 3d objects with .osb format and import Harmony rendered(previously I had version 12 with this script but it was for old maya version).

I would need your help in providing me with the script for maya 2019, thank you very much. My operating system is Mojave OSX
