How can I hide the statusbar?

I'm trying to hide the statusbar on KT3 firmware 5.8.7.0.1.

As a side thing I want to find all the possible properties of an object. (The json that we send to lipc-set-prop, how do people find those? I'm trying words at random that could make sense, is there a better way?

To hide it,

I've tried old methods as interrogatePillow with nativeBridge.hideMe(), didn't work.

I've tried calling lipc-set-prop com.lab126.chromebar configureChrome with many random commands {hidden:true}

I've tried calling lipc-set-prop com.lab126.pillow displayChrome. But It looks like I need to know what to send it.

There's also com.lab126.pillow dismissChrome.

Any hints?
