How to install plugins for vscode's prettier extension?

I want a dev env for my hugo project. This dev env should provide me with vscodium and a bunch of extensions.

Below I pasted my flake which works but is missing prettier-plugin-go-template and I don’t know how to specify it. This plugin for the prettier extension would format go-template files.

I also don’t necessarily want to write my own dev env so if someone already wrote one for this specific task I’d be glad to adjust/use that.

{
  inputs = {
    nixpkgs.url = "github:NixOS/nixpkgs/nixos-unstable";
    flake-utils.url = "github:numtide/flake-utils";
  };

  outputs = { self, nixpkgs, flake-utils, ... }:
    flake-utils.lib.eachDefaultSystem (system:
      let
        pkgs = nixpkgs.legacyPackages.${system};
      in
      with pkgs; {
        devShells.default = mkShell {
          buildInputs = [
            (vscode-with-extensions.override {
             vscode = vscodium;
              vscodeExtensions = with vscode-extensions; [prettier-plugin-go-template
                github.github-vscode-theme
                vscodevim.vim

              ];
            })
          ];
        };
      }
    );
}
