I have a status bar application. The problem is that my icon stay white at all times. Is there a way to make it go white on dark background and black on light backgrounds. I notice that must status bar apps have this feature
class AppDelegate: NSObject, NSApplicationDelegate {
    static private(set) var instance: AppDelegate!
    lazy var statusBarItem = NSStatusBar.system.statusItem(withLength: NSStatusItem.variableLength)
    let menu = ApplicationMenu()
    
    func applicationDidFinishLaunching(_ notification: Notification) {
        AppDelegate.instance = self
        statusBarItem.button?.image = NSImage(named: NSImage.Name("E22"))
        statusBarItem.button?.imagePosition = .imageLeading
        statusBarItem.menu = menu.createMenu()
    }
}
