Customizing loading, permission, etc UI screens?

Hi Zapworks community!

Hey, is there a way to customize the UI screens Zappar sets for us? I would like to change the UI of those screens:
‘permission request’,
‘permission denied’
‘incompatible browser’

Reason 1 is I am making an AR mural in a foreign country in which english is not the main language spoken here and would like to have something a little more local…

Reason 2 would be to craft an experience more aesthetically consistent from beginning to end.

Somebody managed to do this before?
