Nix channel for FreeBSD kernel

[BingWithLessSandwich]

Tried to install a test package after setting it up with the channel nixpkgs https://nixos.org/channels/nixpkgs-23.11-darwin and running this command to install the brave browser sudo nix-env -iA nixpkgs.brave, and i got this error.

error:

Is it the problem that i need to set up a Nix channel specific for the FreeBSD kernel (if it is please tell me)?
If it isn't what it is?

Doesn't look like Nix packages work under FreeBSD without some additional provisioning: https://github.com/nixos-bsd/nixbsd

Never tried it though so I might be wrong.
