Hyprland in QEMU VM - "SUPER" key passthrough

I wanted to try hyprland in a VM. So I created a simple configuration and ran nixos-rebuild build-vm followed by result/bin/run-nixos-vm. That started QEMU, but then I couldn’t do anything because the “SUPER” key (i.e., Windows key) that hyprland uses by default isn’t passed through to the guest OS. I was wondering if that’s something that can be changed by configuration, or it’s just the way it is.
