How to display value NAME instead of value ID in yii2 widget select2?

I have this code:

<?=
    Select2::widget([
   'name' => 'user',           
   'maintainOrder' => true,
  'data' => yii\helpers\ArrayHelper::map(\app\models\Time::getEmployeeUsers(), 'id', 'name'),
                'value' => Yii::$app->user->id,
                'options' => ['multiple' => false, 'placeholder' => 'Select Clients ...'],
                'pluginOptions' => [
                'allowClear' => true,
              ],
                 ]) ?>

I want by default the value to be the person who is signed in. However how the code is now, it displays all users for me, so the user is free to use the data dropdown menu and select another user. I don’t want this to be possible, I want the value to be fixed. If i remove the ‘data’ property, I just get the ID of Yii::$app->user->id whereas I want to display the name. What can I do pls??

It depends on your User model.
For example:

'value' => Yii::$app->user->identity->name,

or

'value' => Yii::$app->user->identity->firstname . ' ' . Yii::$app->user->identity->lastname,
