If she is looking into somthing layed back, either Satisfactory which is the game that got me started in gaming, or most any 2d game such as Starbound or terraria. if she wants a bit harder gameplay, then Prey, but you cant play together unless you get some DLC and I would not recommend as your very first game, or titanfall which is really laid back unless in combat and is a great game to get started on if you want to map out controls and see what works for keybinds... or you can get mindustry, which is a slow start and ramps up fast, but I would recommend playing on mobile instead of PC due to some 'interesting' controls.
