[PRISM] Navigation in Tabbed Page

In my MainTabbedPage I have this:

In UsersPage I have a ListView. Thus, when user click on an item, it opens a detail page.
However, when the detail page appears, the tabs (Main, Group and Users) still there in the layout.

I want the same navigation effect of Facebook Messenger App and WhatsApp.
When the detail page (their conversation page) open, it opens over the Tabbed Page.

I've tried without this:

But navigation doesn't work properly. Actually, this way, detail page opens like a modal and not a navigation page.

Any idea?
Thank you.
