Mounting Second SSD on boot

Hello, I have a second SSD(nvme0n1) that I want to mount on boot under my user. I will mostly be using this drive for storage purposes. Is there anyway I can declare this in my configuration.nix. The drive is currently empty so I am fine with wiping it too.

I managed to fix it myself by mounting the drive wherever I wanted it using gnome disks and then i ran nixos-generate-config.
