How would I create a menu in AR that would let the user select a button and drop a specific mesh that is attached to that button in ARKIT?

I am trying to develop an AR app that should let users drop 5 different meshes into the scene. So far the meshes get randomly generated each time the screen is touched. Is there a way to make it so the user selects a button and then is able to drop a specific mesh that is attached to that button?

I would also like the user to be able to erase the scene and then place a mesh down on a clean screen, is this also possible?

Thanks.

Use a combo box in a widget to make the selection then spawn the selected actor. To clear the scene you could either delete all spawned actors or just simply restart the level.
