My item in hidden because soft regicted but i don’t see the button to update it ???
At first fix all of the issues mentioned by the reviewer then go to edit the item from your Hidden Item and resubmit the update.
If the required modifications are made, it will turn into public or can be hard rejected?
If you fix all issues then most probably the item will be approved or will come another soft reject with other issues (if reviewer find). without the required changes again and again resubmit can be hard rejection.
