CameraUsedInHLArUcoExample

[ShawnZhou997]

Hi,
thank u for sharing the amazing repo for us.
I am using it for some work recently. There is a question: when i try to use only the secondary scene, HLArUcoExample, instead of entering it from the Main scene, the camera can be invoked on PC but cannot be awaken on my HoloLens2 after deployment.
To reduce the memory usage, it is a must that i use only the secondary scene named above.
Here is the normal condition on PC.

Can you help me with this? Thanks again!
