如何在swift / SwiftUI中为滑动手势设置菜单栏图标的操作

Question

I'm trying to get a small test app I'm working on to pop up a mini window with a swiftUI view when the menubar icon is swipe down on. Rather than clicking on the button for the window to pop up, a two finger swipe down as if the user pulled down on the icon for the window to show up. I'm still a bit new to swift but I have the following so far in the AppDelegate.

if let button = statusBar.button{
      let iconImage = NSImage(named: NSImage.Name(("iconPic")))
      button.image = iconImage
      button.action = #selector(self.handleOpenPlayerDescriptionWindow(_:))
      button.sendAction(on: .swipe)
//      button.sendAction(on: .leftMouseDown)
    }

 @objc func handleOpenPlayerDescriptionWindow(_ sender: NSMenuItem){
//code to show swiftUI Window 
...
}

The pop-up window is simply just a placeholder Text view with an NBA player's game stats. I've commented out the sendAction with ' leftMouseDown ' in the code above because that works perfectly fine, but when I change it to ' swipe ' as a sendAction , it does nothing. I've also tried ' beginGesture ', ' endGesture ', and ' gesture ' but all didn't work, the closest success was ' leftMouseDragged ' but not really what I'm going for.

I'm using SwiftUI and not storyboard if maybe that's the issue

There is limitation of this method, as documented only specific masks are checked by this method, swipe is not.
