Guardian System

Thanks for the guardian system - it sounds great. Of course I am very eager to implement it for the ShadedPath DX12 engine. But some things do not seem to be like is documented on https://developer3.oculus.com/documentation/pcsdk/latest/concepts/dg-guardian-system/

•  There is no Guardian code sample in SDK/Samples/GuardianSystemDemo
• I tried to enable the Guardian system in developer mode like described via registry key. I could not see anything anywhere. The guardian system should kick in transparently, right? Applications do not need to draw boundaries themselves? At least that is what I understand from this sentence in your documentation: After the user sets up the boundaries, they will show up in a layer over any application whenever the user gets too close
• I do not own touch, but installed 1.8 runtime. I reran the whole setup, but no questions was asked for marking my safe zone. Does this only work when touch controllers are connected?
• In the engine I could call ovr_RequestBoundaryVisible() successfully, but to no apparent effect - there is still nothing displayed related to space boundaries in any scenario.

Maybe I understood some things wrong. Ayn help appreciated!
