Visual Studio snippet - How to convert first letter to lowercase

Question

In Visual Studio, I would like to update the fullprop snipped to automatically convert the field name according to property name: (and so only enter "property name" & "type")

public string MyTest
{
    get => _myTest;
    set
    {
        if (_myTest == value) return;
        _myTest = value;
        RaisePropertyChanged();
    }
}
private string _myTest;

I can't find a way to convert MyProperty in myProperty. I found this topic which seems to work with VSCode but it doesn't work in Visual Studio. Snippet in VSCode seems to be different from Visual Studio as $1$ works in visual studio but ${1} doesn't work. So is there an equivalent way in Visual Studio ?

Thanks for your help !
