[ARCORE] AR Template - How perform Line trace Components for BP spawned on ARCORE Plane [Screenshot]

Edit: Solved, see next post.

Hi, need help for starting with AR development.
I can spawn my own Unreal Studio Datasmith BP with all geometries inside.
Then i want to see metadata inherited into the BP, I Can perform linetrace but cannot have any hit result.
Is there any method to perform a second level hit component ( the first is to spawn main object into the ARCORE Plane ).
Please see screenshots below.

PS is there any method to see Live camera of my Android phone to realtime debug the project?

Thanks in advance
