Ionic 4 Angular, menu + tabs example

Hi does anyone have an example of an ionic 4, Angular app that has a menu + tab pages but the tabs will direct to different pages depending upon if they are logged in or not? How would the lazy loading work? Should the pages just share a tab component and inside the tab pages, show conditional content?

Have you seen the Ionic Conference App? It does just that:

We’ll be using Ionic and Angular for this example, but as Ionic components are standard Web Components, the process is similar across frameworks.
