How to convert WorldSpace to SolverSpace / Component location for Ikinema

Convert actor WorldSpace vector to SolverSpace / ComponentSpace for Ikinema

I am using the Ikinema plugin. My goal is to transform the IK-Hand of my character to another actor in worldspace.

The Ikinema node need a vector is solverspace as far as I understand. I cannot connect the worldspace (get actorlocation) vector to this node. I cannot figure out how to convert this actorlocation to a location in this solverspace or componentspace.

Hopefully somebody can give me some help. This keeps me busy too long…
