Where to specify small icons (for notifications in status bar) in config.xml?

Android 5.1 expects a white-on-transparent icon for status bar.

App icon is with full color, and those for notifications are in white-on-transparent.

So there should be two distinct zones in config.xml to provide both style of icons.

However, I have only this, thus mixing both styles:

<icon src="resources/android/icon/drawable-ldpi-icon.png" density="ldpi"/>
        <icon src="resources/android/icon/drawable-mdpi-icon.png" density="mdpi"/>
        <icon src="resources/android/icon/drawable-hdpi-icon.png" density="hdpi"/>
        <icon src="resources/android/icon/drawable-xhdpi-icon.png" density="xhdpi"/>
        <icon src="resources/android/icon/drawable-xxhdpi-icon.png" density="xxhdpi"/>
        <icon src="resources/android/icon/drawable-xxxhdpi-icon.png" density="xxxhdpi"/>

Where should I specify the white-on-transparent icons for notifications zone only ?
