How to add store selector multi select field in admin form without using ui component?

Question

I am trying to get store selector in admin form. I created this form without using ui component. I tried the below code but it didn't worked and I got the below error.

The expected input field is:

enter image description here

The input field code is:

$fieldset->addField(
 'store_view',
 'Magento\Store\Ui\Component\Form\Field\StoreView',
 [
 'label' => __('Store view'),
 'name' => 'store_view',
 'disabled' => false,
 //'class' => 'Magento\Store\Ui\Component\Form\Field\StoreView',
 'values' => $this->options->toOptionArray()
 ]
 );

In the above code $this->options is "Magento\Cms\Ui\Component\Listing\Column\Cms\Options" class object.

The error is:

1 exception(s): Exception #0 (InvalidArgumentException): Magento\Store\Ui\Component\Form\Field\StoreView doesn't extend \Magento\Framework\Data\Form\Element\AbstractElement

Exception #0 (InvalidArgumentException): Magento\Store\Ui\Component\Form\Field\StoreView doesn't extend \Magento\Framework\Data\Form\Element\AbstractElement #1 Magento\Framework\Data\Form\AbstractForm->addField() called at [vendor/magento/framework/Data/Form/Element/Fieldset.php:214] #2 Magento\Framework\Data\Form\Element\Fieldset->addField() called at [app/code/Vital/CustomisedIntegrations/Preference/CustomisedForm.php:104] #3 Vital\CustomisedIntegrations\Preference\CustomisedForm->_addGeneralFieldset() called at [vendor/magento/module-integration/Block/Adminhtml/Integration/Edit/Tab/Info.php:53] #4 Magento\Integration\Block\Adminhtml\Integration\Edit\Tab\Info->_prepareForm() called at [vendor/magento/module-backend/Block/Widget/Form.php:156] #5 Magento\Backend\Block\Widget\Form->_beforeToHtml() called at [vendor/magento/framework/View/Element/AbstractBlock.php:1110]

Try this code

public function __construct(
 \Magento\Backend\Block\Template\Context $context, 
 \Magento\Store\Model\System\Store $systemStore,
 array $data = []
) {
 $this->_systemStore = $systemStore;
 parent::__construct($context,$data);
}
 $fieldset->addField(
 'store_id',
 'multiselect',
 [
 'name' => 'store_id[]',
 'label' => __('Store Views'),
 'title' => __('Store Views'),
 'required' => true,
 'values' => $this->_systemStore->getStoreValuesForForm(false, true),
 ]
);
