Fix the issue on Demo web app (Food Related)

It is a demo website built on Angular JS merging fuse templates for learning purpose and I have some issues doing firebase authentication as well as routing and other features. So the base of the code is already built and the following features needed to be updated. 1. Admin component needs to be added where admin can edit the user (delete /verify), user recipes and see the incoming feedback from contact page. It should be done using role based authorization as only users role with admin can only access the page. 2. Route guards should be present so that user cant access features like profile without logging in. 3. A button to activate to pro user should be there. Once clicked user have extra features along with existing features of the app. The extra feature can be anything. Be creative even if its minor change.
