OrbitAnimation does not work.

Hi, I implemented it as shown in the link below, but it does not animate. https://developer.apple.com/videos/play/wwdc2023/10080/?time=1220

The following message was displayed No bind target found for played animation.

import SwiftUI
import RealityKit
 
struct ImmersiveView: View {
    var body: some View {
        RealityView { content in
            if let entity = try? await ModelEntity(named: "toy_biplane_idle") {
                
                let bounds = entity.model!.mesh.bounds.extents
                entity.components.set(CollisionComponent(shapes: [.generateBox(size: bounds)]))
                entity.components.set(HoverEffectComponent())
                entity.components.set(InputTargetComponent())
                
                if let toy = try? await ModelEntity(named: "toy_drummer_idle") {
                    let orbit = OrbitAnimation(
                        name:"orbit",
                        duration: 30,
                        axis:[0, 1, 0],
                        startTransform: toy.transform,
                        bindTarget: .transform,
                        repeatMode: .repeat)
                    
                    if let animation = try? AnimationResource.generate(with: orbit) {
                        toy.playAnimation(animation)
                    }
                    content.add(toy)
                }
                content.add(entity)
            }
        }
    }
}
