Change color or shape of original target-square.

[Vegi Woo]

Describe the bug
Can't change the color of the target square and the shape (if I don't really like the square)

To Reproduce

class CustomARView: ARView {
    var focusEntity: FocusEntity!

    required init (frame frameRect: CGRect) {
        super.init (frame: frameRect)

        focusEntity = FocusEntity (on: self, style: .classic (color: .red))
// оr focusEntity = FocusEntity (on: self, style: .colored (onColor: .white, offColor: .gray, otherColor: .blue, mesh: MeshResource.generateSphere (radius: 0.5)))
   
        focusEntity.delegate = self
        focusEntity.setAutoUpdate (to: true)
    }
    
    @objc required dynamic init? (coder decoder: NSCoder) {
        fatalError ("init (coder :) has not been implemented")
    }
}

Expected behavior
Change the color or shape of the original target square.

Environment:

• iOS Version - 14.1
• Device Information - iPhone XS Max
• macOS Version - BigSur beta 11
