Currently it looks like this https://www.skyscrapercity.com/attachments/cogiteon-19-krak%C3%B3w-07maj2024-jpg.7184543/, so it is not accessible from the outside. I did not try to get there by the visible elevator.

The viewing point was supposed to be the main attraction of the building. But despite the building being opened a long time ago, it is still inaccessible. :-(

Looking at the roof plan https://cogiteon.pl/wizyta/mapa, it seems that it will actually be accessible (along with the elevator) only for special events (there is also a third entrance directly from the terrace https://www.skyscrapercity.com/attachments/cogiteon-20-krak%C3%B3w-07maj2024-jpg.7184550/)
