Applying landmarks to 3D animation in unity

I am generating 33 landmarks of human pose from a video and exporting it to unity. I have imported one avatar in unity which is modelled to be a humanoid.

Now I want to apply those pose landmarks to this humanoid and recreate the motion in video. I am using bone transform from the animator in the humanoid model in my c# script but its not working. The body is not moving. How can I apply these landmarks on this avatar to recreate the same motion from 2d video from my c# script?
