I'd like to remove my Beta of iOS 13

So I installed the IOS 13 beta on my iPhone 7 a while back but with the recent release of the actual IOS13 I would like to remove the beta, I have went into my settings>General, but there is no “profiles” option. Also the “feedback app” is still on my phone? How do I remove the beta?
