Naruto had enough Tailed Beasts' chakra after the battle against Sasuke to undo the Infinite Tsukuyomi together with him, so it's safe to assume he kept it (in battle-to-the-death sutuation he must've used all the chakra he had, incuding his own, TB chakra, Six Paths chakra etc, but after this battle we see that he still has the TB chakra). And even if Hagoromo's chakra gift was temporary, Naruto still has his SPSM, thus the Six Paths (Sage) chakra too, so it mixed into his own, after all, and now he's able to create it all by himself.
