JavaScript from custom module not detected

I have created a custom module, which is working. Except the JavaScript, which is not being detected. I have been following the description at https://www.drupal.org/docs/8/api/javascript-api/javascript-api-overview and I have checked other modules.

What have I done to implement JavaScript? I have created a file with the following JavaScript content (location: MODULE-ROOT/js/info.js):

/**  * @file  * Info behaviors on node edit form.  */  (function ($, window) {    'use strict';    Drupal.behaviors.nodeEditForm = {     attach: function () {       console.log('Hi there!');     }   };  })(jQuery, window);

Then I have added the following content into my MODULE-NAME.libraries.yml file:

nodeEditForm:   version: 'VERSION'   js:     js/info.js: {}

I expect to see “Hi there!” in my webdeveloper tools inside Google Chrome browser, after I flush the entire Drupal 8 and browser cache. I do not get any output there.

Is it a “must” to attach the JavaScript to any existing behavior? If so: how can I learn which behavior is tied to an node edit form?

Thanks for your attention.
