I get soft reject in my Laravel project. Need help.

I got this mail from CodeCanyon.
I check every route/page of my project, I don’t see 403 page.
Now, how do I fix this issue? I test my project on the server and localhost. I try two different servers and I don’t find any 403 pages.

Please help me…

if it is a full application then provide a full design 403 page where visitor should have option to get back to home page (button/link).
