if you try to add an element to a set that already contains the element, will it simply skip it? talking about set → add node
if you push an array into a non empty set via set add items node, and the array contains elements already in the set, will the entire operation fail or will it simply skip those elements already in the set?
If you have 1,2,3 and push in 2,3,4, you will end up with 1,2,3,4 - in this instance chatGPT is correct. I sense I misunderstood the original question.
