I don't know the newest code, but you find the code by opening the file resources/app.asar in Notepad (or similar) and then you search for the following term:
[tb_eval exp="f.Reset='
The cheat code is the word directly after that string in the code. You need to enter it exactly as written in the code (i.e. it's case sensitive). The GUI will often display your code in capitals, whatever you write. Disregard those.
