What is review policy of codecanyon about something that is new or I created it?

Flutter-web is relatively new. I worked really hard to create a head start for my fellow developers and created a login in flutter-web.
Review team didn’t have a category where it could fit so they rejected it and after many attempts, they instructed me to put into HTML5 category for now
Later, when I submitted the code, they HARD rejected it as it’s not up to standards.
Something that is new, has no standards yet and guess what, I cannot re-submit this ever.

Any thoughts from my fellow authors?
