First time set up of hangul and pinyin

Help
1

Hi, and thank you for taking the time to read this. I am currently experimenting with learning either Korean, or Mandarin Chinese. I am currently trying to create a configuration to be able to write in both as needed. Currently I cannot seem to get anything to work, at all. And since I have no experience working with these systems before using nix. I am really struggling to tell if it is a NixOS configuration issue or a language specific issue. Below are the changes I have made to my configuration based on the manual, and a few other posts I have found.

Link to my configuration: GitHub - IronShark-Studios/Technonomicon: Personal System Configurations

utf.nix a sub file of my configuration.nix

    supportedLocales = [ 
    "en_US.UTF-8/UTF-8" 
    "zh_CN.UTF-8/UTF-8" 
    "ko_KR.UTF-8/UTF-8" 
    ];

    inputMethod = {
#    enabled = "ibus";
#    type = "ibus";
#    ibus = {
#      engines = with pkgs.ibus-engines; [ libpinyin hangul ];
#      };
    enable = "fcitx5";
      fcitx5.addons = with pkgs; [
        fcitx-gtk
	fcitx-chinese-addons
	fcitx-hangul
	fcitx-configtool
      ];
    };

I did originally try with ibus but most resources seemed to talk more about fcitx5. I left it in as comments incase it was needed latter.

bash.nix

  programs.bash = {
    enable = true;
    loginShellInit = "
      export XMODIFIERS=@im=fcitx
      export GTK_IM_MODULE=fcitx
      export QT_IM_MODULE=fcitx
    ";
  };

hyprland.conf

input {
    kb_layout = us,kr
    kb_options = caps:swapescape,grp:alt_9_toggle
    follow_mouse = 2
    sensitivity = 0
    touchpad {
        natural_scroll = no
    }

the alt 9 was a temporary keybinding. My goal was right alt caps lock / escape. Not sure how that is counted since I switched it.

Any and all help is appreciated. Both with getting what is currently shown working. Or with managing these types of system in general if you have experience. As I am currently very lost.
