Why does phpStorm strike out "className" syntax in yii2?

Question

Yii

Greetings, I understand that some functions have changed due to the update of yii2, and ::className()
here is an example of what I mean:

The documentation advises to change to ::class()
But I do it

<?= $form->field($model, 'text')->widget(Widget::class(), [
        'settings' => [
            'lang' => 'ru',
            'uploadOnlyImage' => true,
            'validatorOptions' => ['maxSize' => 40000],
            'minHeight' => 200,
            'plugins' => [
                'imagemanager',
            ],
            'imageUpload' => Url::to(['/admin/news/image-upload']),
            'imageManagerJson' => Url::to(['/admin/news/images-get']),
        ]
    ]); ?>

And it gives me an error:

syntax error, unexpected '('
1. in C:\Users\acer\OSPanel\domains\medicalyii2\modules\admin\views\news\_form.php at line
/* @var $form yii\widgets\ActiveForm */
?>
 
<div class="user-form">
 
    <?php $form = ActiveForm::begin(); ?>
 
    <?= $form->field($model, 'title')->textInput(['maxlength' => true]) ?>
 
    <?= $form->field($model, 'text')->widget(Widget::class(), [
        'settings' => [
            'lang' => 'ru',
            'uploadOnlyImage' => true,
            'validatorOptions' => ['maxSize' => 40000],
            'minHeight' => 200,
            'plugins' => [
                'imagemanager',
            ],
            'imageUpload' => Url::to(['/admin/news/image-upload']),
                
2. yii\base\ErrorHandler::handleFatalError()

Please help me figure out how to call this function.

Because the developers considered it depricate and made the right decision to use the native expression that appeared in the 5.5.0 version of PHP
Widget::class
