How to figure out where prefab is being referenced in gameobject?

- I have a prefab in the Assets in the Project view

- If I right click on it, there's an option for "Find References in Scene"

What does that do? When I click on it, the hierarchy search field is set to "ref:Assets/Prefabs/PopUps/PopUpWindow_HelpLinks.prefab", and the only result found is a random gameobject. I'm guessing that this gameobject is somehow referencing the prefab, but how do i figure out where it is beingreferenced? I can't see it referenced in any of the scripts the gameobject has.
