How do I add an amazon embed code in EasyBlog article?

Hi,

I want to add some amazon books to my website but I cannot see hot to achieve this. I basically want to embed this code so the link to the actual book appears:

<iframe type="text/html" width="336" height="550" frameborder="0" allowfullscreen style="max-width:100%" src="/https://read.amazon.co.uk/kp/card?asin=B00L7ULELG&asin=B00L7ULELG&preview=inline&linkCode=kpe&ref_=cm_sw_r_kb_dp_qK3IxbNS9BAYH" ></iframe>

When I paste the text into html block nothing happens, when I paste it into a coded block it just shows the code.

Is it not possbie to insert this kind of thing?

Kind regards

Mel
