Hey man. I know that Hashnode uses the Embedly API. The documentation of the original library is here: https://docs.embed.ly/docs/embedly-api So I assume this particular website does not support being rendered with an enhanced display. For example YouTube uses oEmbed. You can contact them to double check but in general I'd say that if it does not support it you can either try the iframe method or "fake it" with a picture and a link.
