How to convert a Canva template into pure HTML.

[TangledPubes]

I created an email template in Canva. When I try to embed the code to copy it to my email manager, the template is sent but Canva's advertisement 'this was created in Canva' appears in the email footer, even though I have a premium account.

I attempted to extract the source code to remove the footer, but when I run it, only the plain text is displayed without any formatting, CSS, images, everything is locked.

Is there a way to use the source code without the advertisement or share it without the branding? Any suggestions on how to accomplish this?
