Yii2 Custom http exceptions views

Question

In the application login I have the following code that throw ...HttpException on logging errors:

// common/models/LoginForm.php which is called from the backend SiteController actionLogin method as $model = new LoginForm();

public function loginAdmin()
    {
      //die($this->getUser()->getRoleValue()."hhh");
      if ($this->getUser()->getRoleValue() >= ValueHelpers::getRoleValue('Admin') && $this->getUser()->getStatusValue() == ValueHelpers::getStatusValue('Active')){
        if ($this->validate()){
          return \Yii::$app->user->login($this->getUser(), $this->rememberMe ? 3600*24*30:0);         
        }
        else{
          throw new \yii\web\NotFoundHttpException('Incorrect Password or Username.');

        }       
      }
      else{
        throw new \yii\web\ForbiddenHttpException('Insufficient privileges to access this area.');
      }
    }

It is working fine, but I want to customize the page the rendered with each of NotFoundHttpException and ForbiddenHttpException. I tried to search the Yii2 api to find any parameters that may define view in the construct of the object but I could not find that. So, is there any way to custom the view of the exception?

From Mihai P. (Thank you) answer, I have got this answer. I opened the file of the error class at vendor\yiisoft\yii2\web\ErrorAction.php and I have found that it has a public property for view, so, I decided to use it and hence I defined it in the error array of the actions method as follows:

public function actions()
    {
        return [
            'error' => [
                'class' => 'yii\web\ErrorAction',
                'view' => '@common/views/error.php',
            ],
        ];
    }

Finally, in common folder I had to create a new folder named views and fill it with a view file called error.php with the following simple code

<?php
$this->title = $name;
echo $name;
echo "<br>";
echo $message;
echo "<br>";
echo $exception;

The three variables in the view $name, $message and $exception are supplied from the ErrorAction object and they could be found in the last lines of that file

...
else {
            return $this->controller->render($this->view ?: $this->id, [
                'name' => $name,
                'message' => $message,
                'exception' => $exception,
            ]);
        }
...

If you take a look here https://github.com/yiisoft/yii2-app-advanced/blob/master/frontend/controllers/SiteController.php

You can see that it uses an external action to handle the errors

/**
     * @inheritdoc
     */
    public function actions()
    {
        return [
            'error' => [
                'class' => 'yii\web\ErrorAction',
            ],
            'captcha' => [
                'class' => 'yii\captcha\CaptchaAction',
                'fixedVerifyCode' => YII_ENV_TEST ? 'testme' : null,
            ],
        ];
    }

You can either create your own ErrorAction file that extends the default one and use yours instead of the default one from Yii, or just comment out that action and create a normal actionError and put it in there.
