Can OnlineSubsystemOculus be used in editor or does it only work on builds?

It’s been a while since I’ve been trying to figure out how to access the Oculus Online Subsystem, I tried the sample project included in the Oculus Integration SDK and it has several errors despite it’s been updated a month ago, if you try it with an headset it doesn’t even look like a project made for VR.

Can you please suggest me where to look to find a decent documentation about the Oculus Subsystem?

Can you please tell me if there’s a way to debug it through the editor (seeing friends, account data, etc) without packaging the .apk every time?

Thank you in advance!
