Help with vscode extention

Custom vscode extention is not showing

python = pkgs.vscode-utils.buildVscodeMarketplaceExtension rec {
    mktplcRef = {
      name = "python";
      version = "2024.15.2024091801";
      publisher = "private";
    };
    vsix = builtins.fetchurl {
      #url = "/home/spiderunderurbed/private";
      url = "file:///home/spiderunderurbed/private";
      sha256 = "d425c4a32528ea96059df4e85656f6fa5234c127f1c60ed2e11b6b2d225209c8";
      #unpack = false; 
   };
    dontUnpack = true;
}

This is my extention, I put it into my vscode extentions via:

(vscode-with-extensions.override {
vscodeExtensions = with vscode-extensions; [
# MS-vsliveshare.vsliveshare
# MS-vsliveshare.vsliveshare
python
...      

So how do i fix this? do i need the unpack phase? what do i put in the unpack phase? or just how do i get it working

Fixed, instead putting a .vsix file in my path i renamed it to a .zip
