SwiftUI: MagnificationGesture to zoom in centered on a CGPoint

Question

I have a piece of code that allows you to zoom in and out on a circle with a gradient using the magnification gesture. This works fine if I place my fingers in the middle of the screen and zoom, but if I place my fingers on the edge of the screen and do the magnification gesture, I want it to zoom in on the point in between my fingers. Right now, it still magnifies with the center of the screen as center for the magnification.

How can I modify my code to allow the users to center on the CGPoint right between the placement of their finger?

struct ContentView: View {
    @GestureState var magnificationState = MagnificationState.inactive
    @State var viewMagnificationState = CGFloat(1.0)
    
    var magnificationScale: CGFloat {
        return viewMagnificationState * magnificationState.scale
    }
    
    var body: some View {
        let gradient = Gradient(colors: [.red, .yellow, .green, .blue, .purple, .red, .yellow, .green, .blue, .purple, .red, .yellow, .green, .blue, .purple])
        
        let magnificationGesture = MagnificationGesture()
            .updating($magnificationState) { value, state, transaction in
                state = .zooming(scale: value)
            }.onEnded { value in
                self.viewMagnificationState *= value
            }
        
        
        Circle()
            .fill(
                RadialGradient(gradient: gradient, center: .center, startRadius: 50, endRadius: 2000)
            )
            .frame(width: 2000, height: 2000)
            .scaleEffect(magnificationScale)
            .gesture(magnificationGesture)
    }
}

enum MagnificationState {
    case inactive
    case zooming(scale: CGFloat)
    
    var scale: CGFloat {
        switch self {
        case .zooming(let scale):
            return scale
        default:
            return CGFloat(1.0)
        }
    }
}
