How can I use the Scene Control Methods for scene manipulation #18

Hello,
I would need to change or set the duration of a Scene after the DOM has loaded, because I will use the height of a div, which has variable content.
I tried putting a ref on the scene, but I won't be able to manipulate the props directly.

The scroll magic api has something like scene.setClassToggle(), how would I use that with the Scene Component?

best wishes and thanks,
Hans
