Present component on top of ion-tabs

I want to implement Material Design Feature Discovery.
The implementation of the component itself is not a problem but when I try to display it the ion-tabs component is always on top of it and partially overlays/hides my component.

How can I put my component on top of every other component, like navbar, ion-tabs, ion-fab? Something like action-sheet or alert (Those are always on top of everything else)…

I would basically like to implement a custom overlay component
