Show custom backdrop on present

[peeknick]

Hi, I'm currently experimenting with this amazing library. I noticed that if I define a custom backdrop with a simple opacity transition, this will start animanting only when I'm switching snapPoints.

const snapPoints = useMemo(() => ['8%', '40%'], []);

What if i want the animation to start whenever the present() function is called? In my use case I have only one fixed snap point and I'd like to show the backdrop on mount.
Is this possibile?

Thanks
