I got this controller:

<?php
namespace 

clas extends MagentoSalesControllerAdminhtmlOrder

 public function execute()
 

 echo "TEST";
 

?> 

I want it to call a template. How can I do that?

check the below code

 /**
 * @var MagentoFrameworkViewResultPageFactory
 */
 protected $_resultPageFactory;

 /**
 * @param Context $context
 * @param PageFactory $resultPageFactory
 */
 public function __construct(
 Context $context,
 PageFactory $resultPageFactory

 ) 
 $this->_resultPageFactory = $resultPageFactory;
 parent::__construct($context);

 

 public function execute()
 

 $resultPage = $this->_resultPageFactory->create();
 $resultPage->getConfig()->getTitle()->prepend(__(' heading '));

 $block = $resultPage->getLayout()
 ->createBlock('CompanynameModuleBlockblockname')
 ->setTemplate('Companyname_Module::test.phtml')
 ->toHtml();
 $this->getResponse()->setBody($block);
 
}

In controller:

use MagentoFrameworkAppActionAction;
use MagentoFrameworkControllerResultJsonFactory;
use MagentoFrameworkViewResultPageFactory;
use MagentoFrameworkAppActionContext;
use OXOfferNotifierHelperData;

class Index extends Action


 protected $_resultPageFactory;
 protected $_resultJsonFactory;
 protected $_helperData;

 public function __construct(Context $context, PageFactory $resultPageFactory, JsonFactory $resultJsonFactory, Data $data)
 
 parent::__construct($context);
 $this->_resultPageFactory = $resultPageFactory;
 $this->_resultJsonFactory = $resultJsonFactory;
 $this->_helperData = $data;
 

 public function execute()
 
 if ($this->_helperData->isOfferNotifierEnabled()) 
 $result = $this->_resultJsonFactory->create();
 $resultPage = $this->_resultPageFactory->create();
 $productId = $this->getRequest()->getParam("productId");
 $offerInProductView = $this->getRequest()->getParam("offerInProductView") ?? 0;
 $url = $this->getRequest()->getParam("url") ?? 0;
 //Get the product id for ProductView Page 
 if ($offerInProductView) 
 $productInfo = $resultPage->getLayout()
 ->createBlock('OOOYYYBlockProductView')
 ->setData('product_id', $productId)
 ->setData('offer_in_product_view', $offerInProductView)
 ->setTemplate('OOO_YYY::product/view/offer-notifier.phtml')
 ->toHtml();
 


 $result->setData(['content' => $productInfo]);
 return $result;
