Set up controller driven hands v65

Just got v66 of the SDK for Unity and it's still broken.

I understand it works when making a full build, but if I cant use it to debug stuff in play mode then it's basically unusable for anything other than a quick tech demo or prototype.  I wish they could somehow indicate whether they are even aware of the issue or if they ever plan to fix it, otherwise I'd rather cut my losses with the Meta SDK and switch to the XR Interaction Toolkit.
