What I need do more for CI4 Panel Builder?... "it isn't at the quality standard"

I created a panel builder with codeigniter 4. And I received an email

“Crud4 - CodeIgniter4 Panel Builder” and unfortunately we found it isn’t at the quality standard required to move forward, and you won’t be able to re-submit this item again.
