Itachi gave Naruto Shisui’s eye that had embedded basically “protect Konoha” and would triggered by Itachi’s MS(Which Sasuke had implanted after his death) to use on Sasuke if everything went south. It ended up being used on Itachi himself instead during 4th GNW and that’s how he got out of Kabuto controlling him through Edo tensei. What he used on Kabuto was Izanami, initially created to stop Izanagi, both very powerful with the cost of losing the light in your eye, not Shisui’s genjutsu
