Changing display launguage

General
1

I’m a student in korean.
When i use vscode on my laptop, I can see display launguage(the language of showing message, or setting etc.) from English to Korean with a Korean language Extension.
But In project idx workspace, I can’t change the language from English to Korean. (I installed same extension which i installed in my vscode). And gemini said that he don’t know how to change the language.
In this situation, how can i change my display language?
pls help me

Hi @user11 - is your browser and OS set to display in a Korean language? Can you please share a screenshot of your IDX browser window?

Same question.
The tip is “The ‘ms-ceintl.vscode-language-pack-zh-hans’ extension is not available in Firebase Studio for Web.”

My dev.nix file

# Sets environment variables in the workspace
  env = {};
  idx = {
    # Search for the extensions you want on https://open-vsx.org/ and use "publisher.id"
    extensions = [
      # "vscodevim.vim"
      "redhat.java"
      "vscjava.vscode-gradle"
      "vscjava.vscode-java-debug"
      "vscjava.vscode-java-dependency"
      "vscjava.vscode-java-pack"
      "vscjava.vscode-java-test"
      "vscjava.vscode-maven"
      "MS-CEINTL.vscode-language-pack-zh-hans"
    ];
