iOS Clear Button In Notification

I've always liked how clear button animates in iOS notification center so I took a stab at making similar button animation. I see it can be improved but I thought it's good enough to be my first Dribbble shot!

Prototype is made in Framer.js. Any feedback on code will be very appreciated:)
