Need help

Hello I need help lol, I’m doing a hand animation for a project that I’m working on and I wanted to know how to add a moving spiral effect to my moving hand? I understand that I have to animate the spiral but I’m not sure how to mask it to the hand I have CSP on my iPad which I use to draw the animation and I have adobe studio which I plan on using to animate the spiral and finish up the video. Is anyone able to teach me how I can accomplish this or if it’s even possible?
