SwiftUI ContextMenu: Set shape of shadow or hide it

Question

I want to use a ContextMenu with a round button. If the ContextMenu is activated by a long press, a shadow with the shape of a rounded rectangle surrounds the button. I already tried using .contentShape(Circle()), but that didn't work at all.

Is there a way to hide this shadow or to change the shape of it so it matches the button? Maybe the properties of the underlying UIKit view can be modified?

Thanks for answering!

import SwiftUI

struct ContentView: View {
    var body: some View {
        Circle()
            .frame(width: 100, height: 100, alignment: .center)
            .foregroundColor(.yellow)
            .contentShape(Circle()) //does not work
            .contextMenu
        {
            Button(action: {}, label:
                    {
                Text("Action 1")
            })
            
            Button(action: {}, label:
                    {
                Text("Action 2")
            })
        }
    }
}

You need to set contentMenu shape for context menu preview.

You can do that using: .contentShape(.contextMenuPreview, Circle())
