Hi when i try to change the accentcolor , the color is set but there is no ui update

    public Color SelectedAccentColor
    {
        get => _selectedAccentColor;
        set
        {
            SetProperty(ref _selectedAccentColor, value);
            SelectAccentColor(value);
        }
    }

    private void SelectAccentColor(Color value)
    {
        ColorsHelper.Current.SetAccent(value);
        // OR
        ThemeManager.Current.AccentColor = value;
    }
