A thing that was found out is that having the game set to a different langauge can sometimes make codes not work or behave different. Are you playing the game in the English langauge? If not can you try it and see if the code is still causing you problems? As you say you may have to use the code in a certain way. Try the code in a differnt menu or something like that? I am not certain how this games works, maybe you need to pause the game and use the code within the inventory system? Do you highlight the item you want then use the code?this employee for you?
I tested it and didn't change anything here. it's the same.
unless you have to use it in a specific way.
inside or outside the words item, or e activates before and after deactivates.
is there any right way?
Try doing some of the things in the English language if you are not using that language and see what happens.
