Yii2 Show/Hide kartik treeview nodes

问题

I am using Kartik Tree Manager. I am able to add, remove, update nodes. There is more requirement, that is to show/hide nodes on the basis of user access. i.e. when a user is given a specific node(s) then only that particular node(s) with all the child (if any) should be shown.

What I have done so far?

I have created a table user-node in which I am assigning a node id to a user as shown below

What I want to do

Now I want to show only the specified node with its child node only and hide other nodes to that user

Controller

For now, there are two views in which I am rendering the tree structure but in the future, there shall be more

My front page

public function actionIndex()
{
   if(Yii::$app->user->isGuest){
    $this->redirect(Yii::$app->urlManager->createUrl('site/login'));
    }
   return $this->render('index');
}

Itself tree-manager node controller

/**
* View, create, or update a tree node via ajax
*
* @return mixed json encoded response
*/
public function actionManage()
{
    static::checkValidRequest();
    $data = static::getPostData();
    $nodeTitles = TreeSecurity::getNodeTitles($data);
    $callback = function () use ($data, $nodeTitles) {
    $id = ArrayHelper::getValue($data, 'id', null);
    $parentKey = ArrayHelper::getValue($data, 'parentKey', '');
    $parsedData = TreeSecurity::parseManageData($data);
    $out = $parsedData['out'];
    $oldHash = $parsedData['oldHash'];
    $newHash = $parsedData['newHash'];
    /**
     * @var Module $module
     * @var Tree $treeClass
     * @var Tree $node
     */
    $treeClass = $out['treeClass'];
    if (!isset($id) || empty($id)) {
        $node = new $treeClass;
        $node->initDefaults();
    } else {
        $node = $treeClass::findOne($id);
    }
    $module = TreeView::module();
    $params = $module->treeStructure + $module->dataStructure + [
            'node' => $node,
            'parentKey' => $parentKey,
            'treeManageHash' => $newHash,
            'treeRemoveHash' => ArrayHelper::getValue($data, 'treeRemoveHash', ''),
            'treeMoveHash' => ArrayHelper::getValue($data, 'treeMoveHash', ''),
        ] + $out;
    if (!empty($data['nodeViewParams'])) {
        $params = ArrayHelper::merge($params, unserialize($data['nodeViewParams']));
    }
    if (!empty($module->unsetAjaxBundles)) {
        $cb = function ($e) use ($module) {
            foreach ($module->unsetAjaxBundles as $bundle) {
                unset($e->sender->assetBundles[$bundle]);
            }
        };
        Event::on(View::class, View::EVENT_AFTER_RENDER, $cb);
    }
    TreeSecurity::checkSignature('manage', $oldHash, $newHash);
    return $this->renderAjax($out['nodeView'], ['params' => $params]);
};
return self::process(
    $callback,
    Yii::t('kvtree', 'Error while viewing the {node}. Please try again later.', $nodeTitles),
    null
);
}

How can I achieve it? Any help would be highly appreciated.
