Livereload not working in Chrome using Gulp, what am I missing

I'm trying to use Livereload using Gulp, Sublime Text 3 and Chrome but for some reason it doesn't work. Here is what I did.

1. Installed the Livereload extension in Chrome.
2. Installed gulp-livereload.
3. Setup gulpfile.js.
4. Ran gulp.

What am I missing here? Do I need to install the Livereload plugin for Sublime Text 3?

FYI - The Options button in the Livereload extension in Chrome is grayed-out.

My Gulpfile:

var gulp = require('gulp');
       
var scssPlugin = require('gulp-sass');
var livereload = require('gulp-livereload');

gulp.task('myStyles', function () {
    gulp.src('sass/*.scss')
        .pipe(scssPlugin())
        .pipe(gulp.dest('css'))
       .pipe(livereload());
});

gulp.task('watchMyStyles', function() {
    livereload.listen();
    gulp.watch('sass/*.scss', ['myStyles']);
});

gulp.task('default', ['watchMyStyles']);  

Package File:

{
  "devDependencies": {
    "gulp": "^3.9.0",
    "gulp-livereload": "^3.8.0",
    "gulp-sass": "^2.0.4"
  }
}

This is what I did that worked. I used plugin gulp-connect instead of the gulp-livereload.

1. Installed the Livereload extension in Chrome.
2. Installed plugin npm install gulp-connect.
3. Setup gulpfile.js (see code below).
4. Go to your browser and go to URL http://localhost:8080/
5. Click the liverelaod icon in the browser.
6. Run gulp.
7. Done.

My Gulpfile:

var gulp = require('gulp');
       
var scssPlugin = require('gulp-sass');
var connect = require('gulp-connect');

    
gulp.task('myStyles', function () {
    gulp.src('sass/*.scss')
        .pipe(scssPlugin())
        .pipe(gulp.dest('css'))
        .pipe(connect.reload());
});

gulp.task('connect', function() {
    connect.server({
        livereload: true
    });
});

gulp.task('watchMyStyles', function() {
    gulp.watch('sass/*.scss', ['myStyles']);
});

gulp.task('default', ['watchMyStyles', 'connect']);

Package File:

{
  "devDependencies": {
    "gulp": "^3.9.0",
    "gulp-connect": "^2.2.0",
    "gulp-sass": "^2.0.4"
  }
}
