vscode refuse to recognize my NodeJs module (intellisense) error ts(2307), however, module works just fine

Question

After hours of googling, I just have no other idea :)
VSCode (1.18.61) just refuses to recognize my custom NodeJs module (I am on Windows 10)

As you can see, internal NodeJs modules like 'path' is recognized just fine.

My module package.json

{
  "name": "my_test_module",
  "version": "1.0.0",
  "description": "just a test module",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "author": "me",
  "license": "ISC"
}

My module index.js is horrible simple

class Test {

}
   
module.exports = new Test();

So basically NodeJs is working fine, I am able to see & use my module. Just VSC ignores it for some reason.

I have in my global path, none of them appears to work (including after reboot)

%AppData%\Roaming\npm\  
%AppData%\Roaming\npm\node_modules\ 
C:\Users\USER\AppData\Roaming\npm\
%ProgramFiles%\nodejs\
C:\Program Files\nodejs\

Also I have checked VSC settings related to TS, however, I specifically marked JavaScript as language.

Any help will be greatly appreciated!
