Does Unique Device ID work again?

Hello, I know in past engines, like 5.5, the one I am using now, do not have a node called Unique Device ID, but a node that is labeled “Device ID” or something like that, but it does not output anything but a blank string value. I was curious if 5.7 has Unique device ID again, and if it works in that engine or if anyone is having the same problem in 5.5 or similar engine versions. Any answer will help, thank you in advance!
