ios – Reality kit auto generated collision box appearing below the model

I’m trying to load a rigged 3D model in Reality Kit. I was able to load it but the auto generated collision box is placed under the model. And I’m trying to move the model when a button is pressed. How can I do it in Reality Kit. Is it possible to move a 3D model on the detected plane in reality kit

Here is my code

import SwiftUI
import RealityKit
import Combine

struct ContentView : View {
    @State private var yOffset: Float = 0.0
    
   
    @State var btnPressed = false
    var body: some View {
        VStack{
            ARViewContainer(yOffset: $yOffset)
            Button {
                btnPressed.toggle()
                yOffset += 0.1
            //    arView.arView.debugOptions = btnPressed ? [] : [.showPhysics,.showFeaturePoints,.showAnchorOrigins]
            } label: {
                Text("Show Debug")
            }

          
        }
        
       
    }
}

struct ARViewContainer: UIViewRepresentable {
    @Binding var yOffset: Float
    
    let arView = ARView(frame: .zero)
    func makeUIView(context: Context) -> ARView {
        

        
        arView.addGestureRecognizer(UITapGestureRecognizer(target: context.coordinator, action:#selector(context.coordinator.handleTap)))
        context.coordinator.arview = arView
        
        
//        let boxMesh = MeshResource.generateBox(size: 0.05)
//        let boxMaterial = SimpleMaterial(color: UIColor.red, isMetallic: true)
//        let boxEntity = ModelEntity(mesh: boxMesh, materials: [boxMaterial])
//        boxEntity.generateCollisionShapes(recursive: true)
//        let planeAnchor = AnchorEntity(plane: .horizontal)
//        planeAnchor.addChild(boxEntity)
//        arView.scene.addAnchor(planeAnchor)
        return arView
        
    }
    
    
    
    func updateUIView(_ uiView: ARView, context: Context) {
        if let modelEntity = uiView.scene.anchors.compactMap({ $0 as? ModelEntity }).first {
                   modelEntity.position.y += yOffset
               }
    }
    
    
    func makeCoordinator() -> ARCoordinator {
        return ARCoordinator()
    }
    
}

    ContentView()
