Dark icon of macOS app

Please add support for a dark icon to your macOS app. Useful links: https://developer.apple.com/design/human-interface-guidelines/app-icons#Appearances and https://developer.apple.com/documentation/xcode/configuring-your-app-icon#Add-dark-and-tinted-icon-variants-to-iOS-and-iPadOS

I thought macOS dark icon was already supported, maybe only Clear dark?
