Eslint is working from terminal, but not showing error in the editor UI (VSCode)

I've installed the ESlint by following these steps: https://travishorn.com/setting-up-eslint-on-vs-code-with-airbnb-javascript-style-guide-6eb78a535ba6

Now, my ESlint is working from the terminal, but errors/warnings are not displaying in the code window, here is my project structure and how it is looks like:

and my eslintrc configs:

module.exports = {
  env: {
    browser: true,
    commonjs: true,
    es6: true,
    node: true,
  },
  extends: [
    'airbnb-base',
  ],
  globals: {
    Atomics: 'readonly',
    SharedArrayBuffer: 'readonly',
  },
  parserOptions: {
    ecmaVersion: 2018,
  },
  rules: {
  },
};

Why it couldn't show errors in the editor?
