Now we want to start with plus button, we we hit plus button we need to disable plus button and enable the two button. But by default those Item buttons need to be disabled.

We do this using Unity event in Adding_Item_Button.

Now when we press cube button we need to set Placement Prefab from to specific button item.

When we place Object we need to disable the the other button and enable the Adding_Item_Button, Last we need to set Placement prefab to none on AR Placement Interactable.
