PSN points lol

Hi there! when i am on the poe2 or poe 1 website, I see on the top left corner of the website that i have 595 playstation points. it is right next to the in-game points. For the life of me, i cannot figure out how to use the points lol its becoming quite frustrating to be fair and i want to use it on the POE2 game ! thank you in advance for reading this !
