Hover animation not working on my div block button's gradient outline

I’m new to webflow. I made a button with a gradient outline using div blocks. I added a hover animation to the parent div block to rotate the gradient div block 360 degrees on z axis. It is not working at all. When I play back the animation or hover in preview, nothing happens. Can someone help me figure out what I have done wrong?

Here’s a picture of the settings:
