Chess Game Design With Dynamic Animations

Hello, I need help with finishing a Chess Game with animations. I have already created a map environment and all character assets have been done already.

I would prefer to use Mixamo animations for those assets and will need to know / learn how they work.

I need a coder for my chess game to put all that together and release a prototype for my game.
Let me know if you can help

Need it done asap.
