Can't see video when play video using VideoPlayerComponent

Hi,

I am implementing player using RealityKit's VideoPlayerComponent and AVPlayer. When app enter immersive space, playback beigns. But only audio playabck, I can't see video. Do I need specify entity's position and size?

struct MyApp: App {
    
    @State private var playerImmersionStyle: ImmersionStyle = .full
    
    var body: some Scene {
        WindowGroup {
            ContentView()
        }
        .defaultSize(width: 800, height: 200)

        
        ImmersiveSpace(id: "playerImmersionStyle") {
            ImmersiveSpaceView()
        }
        .immersionStyle(selection: $playerImmersionStyle, in: playerImmersionStyle)
    }
    
    func application(_ application: UIApplication,
                     configurationForConnecting connectingSceneSession: UISceneSession,
                     options: UIScene.ConnectionOptions) -> UISceneConfiguration {
        return UISceneConfiguration(name: "My Scene Configuration", sessionRole: connectingSceneSession.role)
    }
}

struct PlayerViewEx: View {
    let entity = Entity()
    
    var body: some View {
        RealityView() { content in
            let entity = makeVideoEntity()
            content.add(entity)
        }
    }
    
    public func makeVideoEntity() -> Entity {
        let url = Bundle.main.url(forResource: "football", withExtension: "mov")!
        let asset = AVURLAsset(url: url)
        let playerItem = AVPlayerItem(asset: asset)

        let player = AVPlayer()
        
        var videoPlayerComponent = VideoPlayerComponent(avPlayer: player)
        videoPlayerComponent.isPassthroughTintingEnabled = true
        entity.components[VideoPlayerComponent.self] = videoPlayerComponent

        entity.scale *= 0.4
    
        player.replaceCurrentItem(with: playerItem)
        player.play()
        return entity
    }
}
