It works. By default, reveal is off. So you need to setup reveal type first. You can access it with the ac_reveal_type parameter. It has two types integer or string but I'm could access only string version so you need to check what the name of reveal type you want to use in your language version.
Btw in your case, I'm not sure it will work with one layer of composite wall. I suppose you need a core to refer to.
