I have this task. I need to implement two buttons, when you press them, the prefab will appear. at startup I can see that the placeable prefab field is updated, but the actual pressing of the button does not happen (I added log output to the console when the button is pressed). I don’t understand what the problem is, because I created the project through AR Core and through 3D. Nothing works. Help, please

I'm trying to make certain prefabs appear when I click on them
