ModalController detail page navigation

When clicking on an item in my modal page, I want to open the detail page for the item.
If I try doing this by using NavController, but then the page gets navigated to in the background (behind the modal background) while the modal stays on top.

I guess the current behaviour also makes sense, since the navController uses the current non modal outlet.

How can I manage to “push” the detail page on top (either completely above the modal – or if not possible that way, at least pushing it on top of the modal nav stack.

Context: Ionic 4 with lazy loading
