How to spawn a Reality Composer scene at the tapped ray touch not ray from center view

Overview

After creating a Reality Composer project, then we can add the 3D content to ARView by calling this code

if let boxScene = try? Experience.loadBox() {
    arView.scene.anchors.append(boxScene)
}

By calling the code above, the scene will be automatically spawned at the ray of center view.

Expected

To make the user feel natural, the App will spawn at the user's tap position. To do so, I started by getting a tap position

Get a tapped position

let arView = ARView()
context.coordinator.arView = arView

// Register tap gesture
let tapGesture = UITapGestureRecognizer(target: context.coordinator,
                                        action:#selector(context.coordinator.tapped(sender:)))
arView.addGestureRecognizer(tapGesture)

//...

@objc func tapped(sender: UITapGestureRecognizer) {
   // Get tap position
   let tapPosition = sender.location(in: arView)
   // call `spawnBoxAt(_)` to spawn a box a ray of user's tap position
   spawnBoxAt(tapPosition)
}

spawnBoxAt(tapPosition)

Experience.loadArrowDownAsync { [weak self] result in
    guard let arrowDownScene = try? result.get() else { return }

    // Perform a raycast
    if let ray = self?.arView.ray(through: tapPosition),
       let results = self?.arView.scene.raycast(origin: ray.origin,
                                         direction: ray.direction,
                                         query: .nearest) {

    // Get the hit against a SceneUnderstanding
    let hitSceneUnderstands = results.filter{ $0.entity is HasSceneUnderstanding }
    guard let hitFirst = hitSceneUnderstands.first else { return }
    let point = hitFirst.position

    // Set position
    arrowDownScene.setPosition(point, relativeTo: nil)
    self?.arView.scene.anchors.append(arrowDownScene)
    arrowDownScene.setPosition(point, relativeTo: nil)
    }
}

Unfortunately, the result of this code arrowDownScene.position is equal to point that was from hitFirst.position but the object is not spawned at tap position but still be at the ray of center view
