ios – Is there a way to observe the content offset of a scrolling SwiftUI Chart?

I need to create a component which enables the users to select a value in a specific date by horizontally scrolling the SwiftUI charts. The image of the component is below.

My code block is as below:

struct SampleModel: Identifiable {
    var id = UUID()
    var date: String
    var value: Double
    var animate: Bool = false
}

struct ContentView: View {
    @State private var data = [
        SampleModel(date: "26\nFr", value: 9.2),
        SampleModel(date: "27\nSa", value: 12.5),
        SampleModel(date: "28\nSu", value: 15.0),
        SampleModel(date: "29\nMo", value: 20.0),
        SampleModel(date: "30\nTu", value: 5.0),
        SampleModel(date: "31\nWe", value: 7.0),
        SampleModel(date: "01\nTh", value: 3.0),
        SampleModel(date: "02\nFr", value: 20.0),
        SampleModel(date: "03\nSa", value: 5.0),
        SampleModel(date: "04\nSu", value: 7.0),
        SampleModel(date: "05\nMo", value: 3.0),
        SampleModel(date: "06\nTu", value: 10.0),
        SampleModel(date: "07\nWe", value: 21.0),
        SampleModel(date: "08\nTh", value: 14.0),
        SampleModel(date: "09\nFr", value: 10.0),
        SampleModel(date: "10\nSt", value: 7.0),
        SampleModel(date: "11\nSu", value: 15.0),
        SampleModel(date: "12\nMo", value: 17.0),
        SampleModel(date: "13\nTu", value: 29.0)
    ]
    @State private var scrollPosition: String = "26\nFr"
    @State var priceText: String = ""

    var body: some View {
        GeometryReader { geometry in
            VStack {
                Text(priceText)
                    .padding()

                Chart(data) { flight in
                    BarMark(x: .value("Date", flight.date),
                            y: .value("Price", flight.value),
                            width: 10.0)
                    .foregroundStyle(
                        Gradient(
                            colors: [
                                .blue,
                                .green
                            ]
                        )
                    )
                    .clipShape(RoundedRectangle(cornerRadius: 16))
                }
                .frame(width: .infinity, height: 180)
                .background(content: {
                    VStack {
                        Color.gray.frame(width: 1)
                        Color.clear.frame(height: 40)
                    }
                })
                .chartXAxis(content: {
                    AxisMarks(preset: .extended, position: .bottom) { value in
                        let label = value.as(String.self)!
                        AxisValueLabel(label)
                            .foregroundStyle(.gray)
                    }
                })
                .chartScrollableAxes(.horizontal)
                .chartXVisibleDomain(length: 11)
                .chartYAxis(.hidden)
                .chartScrollTargetBehavior(
                    .valueAligned(unit: 1)
                )
                .chartOverlay { proxy in
                    
                }
            }
            .frame(width: .infinity)

        }
    }
}

I need to observe the content offset of the horizontally scrolling chart in order to retrieve the centre value based on the position by using proxy of chartOverlay. Is there a way to observe the content offset of the scrolling chart? Or is there another perspective to retrieve the centre value in the scrolling chart?
