Does anyone know what the default "Scroll to Section" animation is?

I have a project where I have to use some custom code to trigger a scroll to section. I have this working fine by doing this:

$('html, body').animate(
    {
        scrollTop: $(targetSection).offset().top
    },
    2000
);

What I would really like to do is to make my scoll animation match the default Webflow scroll animation. Does anyone know what this is?
