How to pull back a package from asset store that's pending review?

I’m a noob when it comes to 3d modeling and I just realized that I made some UV mapping mistakes with my 3d model that is currently pending review, also it had ngon’s and I fixed both of the issues later, but the package is already sent to Unity for review.

So what do I do now, is there a option to cancel this package, do I create a new package with the fixed model and send that as well, do I need to wait for a few days until the bad version gets reviewed and rejected and then try again with the fixed one?

You should be able to create a new draft, upload the new package, and submit it again.
