Undefined index for each text format that the plugin was not enabled.

As soon as i enabled the module i got this error for each text format i had enabled when editing a node.

Notice: Undefined index: wordcount in Drupal\ckwordcount\Plugin\CKEditorPlugin\Wordcount->isEnabled() (line 52 of modules/ckwordcount/src/Plugin/CKEditorPlugin/Wordcount.php).

This seemed to solve it but maybe there is a better way to do it:

  public function isEnabled(Editor $editor) {
    $plugins = $editor->getSettings()['plugins'];
    if (isset($plugins['wordcount'])) {
      return $editor->getSettings()['plugins']['wordcount']['enable'];
    }
  }
