What is the proper way to assign custom email template to specific payment method upon creating an order? For example:

When choosing a Bank transfer payment method on the checkout it should send custom email template upon submiting the order, not the default order email.

I've looked around but found no proper solution for this issue, only this: Magento 2: how to declare a custom email template for your module

A module can be made with below code to override "MagentoSalesModelOrderEmailSenderOrderSender"

File: 'app/code/Vendor/Module/etc/di.xml'

<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
<preference for="MagentoSalesModelOrderEmailSenderOrderSender" type="VendorModuleModelEmailSenderOrderSender"/>
</config>

File: 'app/code/Vendor/Module/Email/Sender/OrderSender.php'

Class VendorModuleModelEmailSenderOrderSender 
namespace VendorModuleModelEmailSender;

use MagentoSalesModelOrder;

class OrderSender extends MagentoSalesModelOrderEmailSenderOrderSender

protected function prepareTemplate(Order $order)

 parent::prepareTemplate($order);

 //Get Payment Method
 $paymentMethod = $order->getPayment()->getMethod();

 //Define email template for each payment method
 switch ($paymentMethod) 
 case 'cashondelivery' : $templateId = 'custom_template_cod'; break;
 case 'checkmo' : $templateId = 'custom_template_checkmo'; break;
 // Add cases if you have more payment methods
 default:
 $templateId = $order->getCustomerIsGuest() ?
 $this->identityContainer->getGuestTemplateId()
 : $this->identityContainer->getTemplateId();

 

 $this->templateContainer->setTemplateId($templateId);
