I’m in the tethered HTC/SteamVR corner so I’m not aware of the options for those that use Meta/Oculus products unfortunately. I mentioned it because people here use all kinds of players and software combinations to play videos and scripts. But it is hard to know what is used for 2D and what is used for VR when ju skim a lot of threads over time.
I searched a bit and Go isn’t really mentioned much. Quest is more common. This thread mentions a possible option although it requires the use of a PC. https://discuss.eroscripts.com/t/unable-to-install-heresphere-on-oculus-go/60503
Another option that cost a little money is the player Pigasus, which is supposed to support funscripts, TheHandy as well as support Oculus Go. Sources for that claim are the product page and the following thread:
