GeometryReader3D and Scene Phases do not work properly.

Hi

Scene Phases, but no event is issued when Alert is executed. Is this a known bug? https://developer.apple.com/videos/play/wwdc2023/10111/?time=784

In the following video, the center value is obtained, but a compile error occurs because the center is not found. https://developer.apple.com/videos/play/wwdc2023/10111/?time=861

    GeometryReader3D { proxy in
        ZStack {
            Earth(
                earthConfiguration: model.solarEarth,
                satelliteConfiguration: [model.solarSatellite],
                moonConfiguration: model.solarMoon,
                showSun: true,
                sunAngle: model.solarSunAngle,
                animateUpdates: animateUpdates
            )
            .onTapGesture {
                if let translation = proxy.transform(in: .immersiveSpace)?.translation {
                    model.solarEarth.position = Point3D(translation)
                }
            }
        }
    }
}

Also, model.solarEarth.position is Point3D. This is not a simple Entity, is it? I'm quite confused because the whole code is fragmented and I'm not even sure if it works. I'm not even sure if it's a bug or not, so it's taking me a few days to a week to investigate and verify.
