Putting an object into "actors" hand AE+C4D


Hello guys, I have searched half of the internet, but to my surprise, I didn’t find any tutorial for this - I need to put an 3d object to my hands (footage will be me, carrying the object and then putting it on the ground), I know how to put objects into space, on the walls etc, but this is a bit more tricky, camera tracking in AE practically completely igonre me in the scene, so it is impossible to attach objects to my hands. Thanks for any help.
