apriltag setup for quest 3

Hello I am working out how to crate an Apriltag system on my quest3 with unity.

id like to play with mesh objects that I crate in Rhino, and would like to place them in the AR.

I want to place tags so I can find my objects back later on. 

In my set up I have a button to pin the object and one to reposition the object.

At the moment I did not succeded yet to project an object onto the tag.

very fruatrating pherhaps I missing something. 

anyone who can help would be great!

thanks
