I looked into this issue for hours and found this software: https://karabiner-elements.pqrs.org/. I was ready to customise the keys, but suddenly the macOS recognised this keyboard after installing that software. Beforehand, I just plugged the keyboard in and started using it as it is wired. Now the key prints out the correct symbols, I guess the issue was that lack of recognition.
