so uh, iirc you need a keycard so you can access the lift that will take you to another place with a big round thingy, to process even further, you must have a cognitor mask so you can interact with the round thingy and you will get another ending. cmiiw
are you unable to use the lift at all? maybe what you found is not a lift that'ss why it's not working, you must hold the keycard and use it on the lift
