How do I add the Widgets menu using “Hello Theme” for Elementor?

To enable the Widgets menu item in the WordPress admin menu, add the following code in your functions.php file

You will then have the Widgets menu available to you, you can then assign Widgets to the Sidebar as usual in Appearance > Widgets.

Note: This may cause a warning in WordPress 5.6. My local version was fine. My server version had an error!
