checkout wordpress plugin refused

hello I sent a wordpress plugin but it was refused and the envato doesn’t tell me why. The plugin changes the look of the woocommerce checkout on any theme, the same can be found on https://demo.joycheckout.com. someone could help me, it was given that I could no longer send the same project because it did not reach the quality standard, and I guarantee that we reached it because it is already sold in other media.

As an exclusive author you would not be able to sell it in multiple marketplaces. This would definitely bless to rejection

mas minha conta diz que eu venderia em outros lugares, como outros plugins e temas que existem aqui. seria mais fácil informar o erro correto? e não vim dizer que não atinge o padrão de qualidade e não posso mais enviar o plugin.
Isso prejudica todo o trabalho árduo que temos.
