I'm a little bit confused about v31 SDK update. Currently, I'm using OVRPlugin in Unity from the integration package, but I will have to move to Oculus XR and OpenXR which is fine. What about the v31 platform SDK? Will it be available in legacy OVRPlugin (which should be the last one)? I want to implement new invite features, but there is still no package update. Do we have to wait a little bit more or I'm just searching wrong?
