UseItemAt Package

Target: The item to be used. It can be in the actor's inventory or in the world near that location.

Location: The location to travel to before attempting to use the target object.

If the idle animation is set up properly, the actor will play the idle associated with the item.

Note: To let a NPC sit in a chair without a reference to the chair you need to use Travel. With a Travel package and Location: Any Object, Furniture the NPC sits on the chair with the highest FormID. UseItemAt does not work all the time here.
