First upload Hard Rejected (CodeCanyon), Please help me

My item was twice soft rejected and when I solved the issues mentioned by the Envato team then it was hard rejected. Kindly help me out with how can I resubmit again, please.

Envato team’s Response: “Thank you for your submission. We have completed our review of ‘PushBluster - The Ultimate Self Hosted Web Push Panel’ 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.”

Not being rude, just trying to understand the product and use case.

Why would someone use this! there are free services out there for the same job I believe.
