Firefox OS - Change screen brightness from privileged app

Question

I'm trying to make a simple flashlight application for FirefoxOS. I need to set screen brightness to high level but according to [MDN][1]

[1]: https://developer.mozilla.org/en-US/Firefox_OS/Platform/Settings_list only certified apps can change these settings.

So is it possible to write a certified application and published it? Or can I change screen brightness in privileged mode?

So is it possible to write a certified application and published it?

Unfortunately not.

See the section in packaged apps about certified apps. Apps published to the firefox marketplace can be privileged but not certified. For more information about the privileges marketplace apps can get, see app permissions.
