What oil for my mini brushless refrigeration compressor?

I bought this mini brushless motor refrigeration compressor off ebay

https://www.ebay.com/itm/394973594549?mkcid=16&mkevt=1&mkrid=711-127632-2357-0&ssspo=NBRwqsD9QwK&sssrc=4429486&ssuid=luojojekr3o&var=&widget_ver=artemis&media=COPY

Ebay says it uses 68hes-h oil. I couldn't find info on this type of oil so i asked chat gpt. That says it is hydraulic oil with a viscosity grade of 68 but that POE is normally used in refrigerator compressors.

Can someone confirm what oil to use for this? POE or a hydraulic oil?

Thanks
