Overlay ignores navigation bar and status bar hide status

**Is your feature request related to a problem? Please describe.**
Using following plugins to hide status bar and navigation bar in our game. We really don't want them to be visible during the game. They are working fine tho.

This issue is not related with those plugins just wanted to mention

https://github.com/ionic-team/capacitor-plugins/tree/main/status-bar
https://github.com/hugotomazi/navigation-bar

When I load intersetial or rewarded video ad this admob plugin is simply ignoring what I set with above and not covering the status / navigation bar area.

**Describe the solution you'd like**
I don't expect this plugin should work smoothly with other plugins but there should be a setting in this repo to hide those bars if we want to

**Describe alternatives you've considered**
none

**Additional context**
nope

The issue names no repository files, tests, or entry points. Reproduce the problem with the linked status-bar and navigation-bar plugins while showing interstitial and rewarded ads, then define done as both system bars remaining hidden during those ad presentations.
