Is it possible to constraint object that will be connected to kinematic object in my geo?

Hey guys, i’m new in rigging, and can’t figure out super simple thing,
I have set of sub-objects.
Like Body/Hand/Tool
Hand is Sub-object of Body, and i need to Constrain Tool to the hand.
Hand and Body is Kinematic objects i don’t need any physics on them, and will do some Anim to it, and can’t find a way to connect physical object to kinematic. is it even possible in UE?

Struggled for this issue more than 1 week. And after write question found the solution.

In Parrent Mesh you need to turn off “Auto Weld”
I guess without this check box it counts mesh as separate element and all constrains works now. crazy…
