HMTL code - Email widgets- to add Trustpilot stars review in my campaign email

Hi , I am having issues when trying to use a HTML code (Email widgets) from trustpilot that is meant to be added in a email in campaign to show the trustpilot stars and review . but after I paste the code, I can see the badge well in the email while I edited but it does not show in the preview and also not in the actual email that gets sent. It just disappears.
I have attached some images to show what I tried to explain.
How can I have this working. I know it used to work before. But since last Friday it does not seem to work.
Thank you,
