I’m not sure that this link really helps your case, given these key points from the description:
The resolution by the British representative, Ambassador Sir Anthony Parsons
demanded an immediate cessation of hostilities between Argentina and the United Kingdom and a complete withdrawal by Argentine forces
Resolution 502 was in the United Kingdom’s favour by giving it the option to invoke Article 51 of the United Nations Charter and to claim the right of self-defence
It also talked about the starting negotiations to discuss the future of the Islands, aka return them (because I doubt they would have gone with a timeshare/co-op plan.
There’s been other UN discussions on the matter as well: https://press.un.org/en/2021/gacol3347.doc.htm

The parts you quoted were about self-defense and stopping the fighting, not about the ownership of the islands.
I quote it because it also talks about negotiations that should be begun when it comes to the ownership of the islands, in lieu of continuing the fighting.
I’m already on record about stating that the fighting was wrong, though I don’t know how long anyone would expect a nation to wait for a diplomatic solution.
This press release from the UN goes into more detail on the basic structure of what I’m arguing about: https://press.un.org/en/2021/gacol3347.doc.htm
(I really shouldn’t bother with attempting nuanced conversation on the Internet, it never ends well.)
Negotiations are great, but surely you realize that Argentina shouldn’t expect (or want) to gain sovereignty over the Falklands?
