It only works with Bitlocker which relies only on external/discrete (dTPM) key material and no configured PIN or password, so there is nothing to input. It’s just sniffing key material off of the external TPM bus after the bootloader asks for it. This is an ancient attack and not very technically interesting, but it comes up every few years because Microsoft still don’t switch to using TPM encrypted sessions.
