Making AI Chase things other than Players?

So I’m very new to this and am not sure what it is I’d need to set exactly so I provided this screenshot to see if I’m even on track:

Like I set the actor/object to something in the world - I copypasted the default thirdperson character with no event graph or anything in it, do I need something in it’s blueprint as well to communicate with this?

Or am I looking in the wrong place entirely, cuz I was under the impression I just needed to get a variable that refers to an object and plug it in though I figure the ‘get player character’ provides more information than just the object (if i change the player character to another object the ai will then read it so it’s just things the player isn’t possessing.
