The object could have interactibility (Interactability Binary_State and stuff, check this [docs.smartlydressedgames.com] ) that also rewards ( check this [docs.smartlydressedgames.com] and this especially flag bool [docs.smartlydressedgames.com] )

After setting that up, your quest condition could have that particular flag_bool ID, that was stated in the file for that interactable object, as a condition. This would make it such that players who haven't interacted with that object cannot proceed to the next part of the quest.
