How can I bring up roscore if the ros packages are installed using homemanager

[konnpaku-youmu]

Hi, I'm pretty new to NixOS and I'm trying to work with ROS1 on NixOS. After successfully installed ros-core with Home Manager, I'm wondering how I can bring up roscore as in other Linux distributions. Has anyone tried the same thing? Thanks in advance.

Here are my nix files:

Home Manager: default.nix

{ config, lib, pkgs, ... }:
{
        imports = [
                ./wayland
                ./modules
        ];
        home.username = "xxx";
        home.homeDirectory = "/home/xxx";
        home.packages = with pkgs; [
                pulseaudio
                pavucontrol

                telegram-desktop

                bottom
                lm_sensors
                pciutils
                usbutils

        ];

        home.stateVersion = "23.11";
        programs.home-manager.enable = true;
}
