How create ObservableProperty with private setter?

[Somov62]

I can't find an example of a private setter implementation anywhere.

Usage scenario without toolkit:

private Project _current = null!;
/// <summary>
/// Редактируемый проект.
/// </summary>
public Project Current
{
    get => _current;
    private set => SetProperty(ref _current, value);
}

Desired implementation:

[ObservableProperty(PrivateSetter = true)] 
private Project _current = null!;
