We'd like to add some simple code to our .reality file but I'm thinking that in order to do that, it needs to become an app. Is this true or can one add code into a Reality Composer scene and then export .reality? Thanks!

Long time listener, first time caller here, We'd like to use AR Quick Look to render a rigged game character that walks to where you tap on the base surface. So far, I'm only seeing the ability to sequentially trigger actions. So move+animate simultaneously seems un-doable. I guess one could parent the USDZ to a "mover" object and then run the transform on the mover and the animation on the USDZ but ugh. Anyone done something like this?
