Display a full sized Gauge on a 10" tablet

I would line to use the Android App (Ver 2022.8.0-full) on a large tablet to show a “Gauge Card”.
However, I would like to display it at about 80% screen size.
Can anyone suggest how to go about this?
I know I can use Chrome and zoom to the size I want but that means that it is all to easy to accidental reconfigure the display.
Regards, M.
