How to play Hollow Knight with a friend: Hollow Knight Multiplayer (HKMP)
See each other in Hallownest, fight bosses together, optional PvP add-on. Mature and well maintained. Steam lists Hollow Knight as single-player, so it won't show up in Steam's own "games we both own" view as something you can play together — Ready Up counts it anyway, marked "Via mod", and you can hide mod-only games with one filter if that's not your thing.
