Issue in adding custom audio plugin ?

[i-internet]

I am trying to add Audio plugin support and I am getting error in console :-

froala-audio.js:3 Uncaught TypeError: Cannot read property 'POPUP_TEMPLATES' of undefined

The code I have added for clientPlugins :-

'clientPlugins' => [
  ......
  ......
  ......
 'video',
        'word_paste',
        'audio' =>[
            'css' => [
                \Yii::$app->urlManager->createAbsoluteUrl([
                    '/plugin/froalaPlugins/audio/css/froala-audio.css',
                ])
            ],
            'js' => [
                \Yii::$app->urlManager->createAbsoluteUrl([
                    '/plugin/froalaPlugins/audio/js/froala-audio.js',
                ])
            ]
        ],

I am using this plugin for Yii2 and this plugin and trying to add for enabling audio feature

I am not sure if I am adding this in a right way
