Hey Guys, I’m quite new to figma (about a week in)

As you can see in the video, I’m presenting the hovering smart animation for my google button, how can i make it so that when it animates to the bigger version of itself, it animates in a centered manner if that makes sense. I’ve tried looking everywhere on figma if theres like a setting but ive probably missed it. Is there any way i can animate the button in the centre. 

Thanks
