Load a template and send an email from a custom module

Problem/Motivation

I want to load a translated template made in Easy Email in a custom module/

Steps to reproduce

This is why I got for now and it's working for the current language.

use Drupal\easy_email\Entity\EasyEmailType;
use Drupal\easy_email\Entity\EasyEmail;

$email_type_id = 'my_template_machine_name';

    $email_type = EasyEmailType::load($email_type_id);
    if ($email_type) {
      $email = EasyEmail::create([
        'type' => $email_type->id(),
        'subject' => $email_type->getSubject(),
        'body_html' => $email_type->getBodyHtml(),
        'body_plain' => $email_type->getBodyPlain(),
        'from_name' => $email_type->getFromName(),
        'from_address' => $email_type->getFromAddress(),
        'reply_to' => $email_type->getReplyToAddress(),
        'recipient_address' => 'email@email.com',
        'cc_address' => $email_type->getCc(),
        'bcc_address' => $email_type->getBcc(),
        'inbox_preview' => $email_type->getInboxPreview(),
      ]);
    }

    \Drupal::service('easy_email.handler')->sendEmail($email);

Two questions :
1) Is is the right way to load an easy email template in a custom module ?
2) How to get a translated version (hasTranslation et getTranslation are not working) ?

Thank you
