White space in header of dashboard in fully kiosk app

Configuration Frontend
1

Hi!

I have been playing with a dashboard in home assistant. It is shown on a Lenovo tablet using fully kiosk.

It works really nice but I have this white space on the right hand side of the header bar.

Any suggestions on how to remove that whitespace and have the header bar extend to the far right side of the screen?

Thanks!

Mark

No suggestions? Did I miss documentation that could help me? Searched everywhere but could not find any clues.
