Working around for proper production Signature

Even after bundling of app andsigning it with Mac Developer Application certificate, still it says the application is from un-identified developer.
So I am figuring out a proper way to sign the app and with proper certificates.
But again these certificates require a higher privelege level, so I have requested my mentor Mr Paul for the same.
Required things Certificate : Developer ID Application
Privelege level: Team-agent
I am guessing that I will be granted the same, and soon will update with proper app.

Hoping for Best.
Happily Coding
