BTA ticket upgrade

So when I first bought GA tickets I bought bite the apple upgrade. A few days ago, I ended up impulsively just buying N1 Obsession VIP Package. I’ve already sold my previous GA ticket but was wondering is there any way I’d be able to sell the BTA ticket upgrade or is it only accessible for the person who originally bought the upgrade? Is there any way around that?

Or am I screwed and just lost the money I paid for the upgrade?

Please let me know bc I heard that it can be sold and that the person who buys it would simply have to take the original buyer’s ID along with their ID but I just wondered if anyone knew if there was truth to that. Please and thank youu
