Bottom navigation bar still visible

[sealover06]

Hello, Great plugin, it does the job, the KioskPlugin.exitKiosk(); works well, shows both launcher3 and my kiosk app. However, a swipe up from bottom in kiosk mode still shows the bottom nav bar.
then a click on the bottom buttons are inoperable, which is ok, but I can still see for instance the power popup flickering for few milliseconds.

Better would be not to see the nav bar at all, even on a swipe up from bottom.
Any idea ?
my device runs Android 7.1.2

Thank you so much.
