❔ Why do my source generated properties are unreacheable in code? using mvvm toolkit

    public partial class CalculatorVM : ObservableObject
    {
        [ObservableProperty]
        private  int buttonOne = 1;

        [ObservableProperty]
        private  int buttonTwo = 2;

        [ObservableProperty]
        private  int buttonThree = 3;

        [ObservableProperty]
        private  int buttonFour = 4;

        [ObservableProperty]
        private  int buttonFive = 5;

        [ObservableProperty]
        private  int buttonSix = 6;

        [ObservableProperty]
        private  int buttonSeven = 7;

        [ObservableProperty]
        private  int buttonEight = 8;

        [ObservableProperty]

        [ObservableProperty]

        [ObservableProperty]
        private Label resultLabel;



        [RelayCommand]
        public void NumbercClicked(int number)
        {
            var selectedNumber = number switch
            {
