Question Join two animated object

Hi,
i created two 3d objects in blender with animation and its intention is to connect them in unity so that the head moves according to the body. The only thing that occurred to me was to connect somehow using a face, but I have no idea how to do it. Could it be done somehow?

Edite: I tried how it could be done in a blender and I found that the control bone of the head and the bone that moves the neck can be connected to each other and it looks quite believable. Is it possible to do the same in unity?
