Creating new markers...

[diramazioni]

Hello,
I'm looking at the only available example and currently trying to replicate it with a new marker.
The getting started section explains how to create a new arMarker in the editor but not how to make the entity spawn.
I've created my pattern , uploaded in the folder playcanvas-ar/artoolkit/pattern/pattern, dragged the asset in the Pattern filename, then I draged in the editor the BlueBox as a children of my new Marker (I've taken it from the Matrix Marker that I still don't understand what is it used for). When I launch on mobile I can see the orange box for the Hiro pattern but not the blue one for mine.
I don't know if simply making the blue box a child of my marker would actually make it work, it seems I'm missing a piece of configuration but I don't see any additional scripts besides playcanvas-ar.js.

Is it possible to trigger an animation, a sound or something else?
