Compass Heading information in RealityKit

I'm new to SwiftUI, and I've learned some basics of my project's RealityKit and ARKit. I just want to display an arrow that always faces towards the north, or at least get heading information displayed as text when I open the camera (AR Experience).

Waiting for someone to solve this fundamental problem.

Thanks in advance!

Use the following code to create AR experience that depends on device's geo position.

Reality Composer

enter image description here

Code

import SwiftUI
import RealityKit
import ARKit

struct ARViewContainer: UIViewRepresentable {
       
    func makeUIView(context: Context) -> ARView {
        let arView = ARView(frame: .zero)
        arView.cameraMode = .ar
        arView.automaticallyConfigureSession = false

        let config = ARWorldTrackingConfiguration()
        config.worldAlignment = .gravityAndHeading       // case = 1
        arView.session.run(config)
        
        let arrowScene = try! Experience.loadNorth()
        arView.scene.anchors.append(arrowScene)
        return arView
    }
    
    func updateUIView(_ uiView: ARView, context: Context) { }
}

struct ContentView : View {
        
    var body: some View {
        ZStack {
            ARViewContainer().ignoresSafeArea()
        }
    }
}

Settings

On device, go to Settings–Privacy–Location Services–On. After that, in Xcode, append Privacy LocationUsageDescription and LocationWhenInUseUsageDescription and then CameraUsageDescription keys in info tab.
