Yii2: Using TinyMCE into Kartik's DetailView with custom settings

I'd like to insert 2amigos' TinyMCE widget in Kartik's DetailView edit mode. This is what I got by now:

       [
           'attribute' => 'myAttribute',
           'format' => 'raw',
           'type' => 'widget',
           'widgetOptions' => ['class' => TinyMce::classname()],
           'value' => $model->myAttribute,
        ], 

With this chunk I managed to show TinyMCE editor with default settings. What I'm trying to do now is to show it with custom settings defined by:

Yii::$app->params['myTinyMceParams']

In form I'm doing this:

<?= $form->field($model, 'myAttribute')->widget(TinyMce::className(), Yii::$app->params['myTinyMceParams']) ?>

Any ideas?
