How to send an e-mail after adding the product to the cart in magento 2?

Unfortunately, so far I am a complete beginner in creating a module in magento.
I need to send an email after adding the item to the cart.

As I understand it, I need to use the checkout_cart_product_add_after event

I created some files, but I don’t understand how to send an email after adding the item to the cart

My/Module/etc/events.xml

<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Event/etc/events.xsd">
<event name="checkout_cart_product_add_after">
    <observer name="email_after_adding_product" instance="MyModuleObserverSendEmailForCart"/>
</event>

My/Module/Observer/SendEmailForCart.php

<?php
namespace MyModuleObserver;

use MagentoFrameworkEventObserverInterface;
use MyModuleHelperEmail;

class SendEmailForCart implements ObserverInterface
{
    private $helperEmail;

    public function __construct(
        Email $helperEmail
    ) {
        $this->helperEmail = $helperEmail;
    }
    public function execute(MagentoFrameworkEventObserver $observer)
    {
        return $this->helperEmail->sendEmail();
    }
}

My/Module/Helper/Email.php

<?php

namespace MyModuleHelper;

class Email extends MagentoFrameworkAppHelperAbstractHelper
{

    public function __construct(

    )
    {

    }

    public function sendEmail()
    {
        try {
            
        } catch (Exception $e) {

        }
    }
}

Please tell, what code I need to write in the Email.php file?
And do I need to create any additional files or modify the ones I showed above?
