Drupal 8.x

Hi on drupal 7 I had the possibility to put an Long IFrame tekst in the body when plain text was selected.

In drupal 8 it seems this is not working I tried several other options:
1 the Iframe module, not working because the IFrame i Need has more fields
2 Url_embed, not working because the field where you can put the Iframe tekst is too short.

How do I get this working ? another module ??

Here the IFrame I need:

I have below code

use Drupal\commerce_order\Entity\Order;

$order = Order::load(<order id>);
if ($total_price = $order->getTotalPrice()) {
  $total_price->subtract(new Price('-5.00', 'USD'));
}

$order_refresh_service = \Drupal::service('commerce_order.order_refresh');
$order_refresh_service->refresh($order);
$order->recalculateTotalPrice();
$order->save();

How to update order total price?

I recently created a drupal module project and messed up the tags and branches on my first attempt to upload. I flagged the first release I had created as unsupported in order to hide it. I then created a new release (new branch, new tag and version number upgraded) that I want to show as supported. However when I install it  and check for udpates it shows as unsupported.
