Path-finding on physics actor


I’m using kind of BP entities for a RTS and I would like to know if it is possible to use the navigation path finding system to help the entities to avoid obstacles.
My entities are based on actor class and are moving using physics simulation (“add force” node).

I find the “Find path to location synchronously”, it returns a Navigation Path var but I don’t know how to extract from it the steps’ location and use it to provide the add force a direction.

I don’t know if it could work actually, nor if it is a good approach, that’s why I’m asking.
Is that possible and how can I do to have path-finding on a physics actor with blueprint?
