Support macOs custom views inside of a menu item

[damageboy]

While not the most common scenario, I'm interested in replicating custom controls inside of a tray menu like this:

If I understand correctly, this can (?) be achieved by overriding the view of the menu item, for example in swift like so:

let menuItem = NSMenuItem()
menuItem.view = NSSlider(value: 0.5, minValue: 0.0, maxValue: 1.0, target: nil, action: nil)
menu.addItem(menuItem)

Is this achievable with muda?

I can't personally work on this since I don't have a macOS but PRs are welcome and I will help in any way I can.
