Oculus Avatar launch incorrect position on Go

I am developing in Unity, followed instructions on official blog (https://developer.oculus.com/downloads/package/oculus-avatar-sdk/) and also did some digging on this issue, honestly the Avatar & Hand should just align correctly with the HMD cam instead of manually adjusting the LocalAvatar transform. Since I have to run the app to see what's changed, this becomes a pain.

Any tips are welcome.
