I would like to tweak the Material UI Mini Variant Drawer code to have the full-sized drawer open (rather than closed) by default on screen sizes large and extra large. It should only show a mini drawer when the screen size is smaller medium or smaller. How do I do this? I have messed about with the code with no joy!
The Material UI code is below, but it's also available on the website here: https://material-ui.com/components/drawers/#mini-variant-drawer
Many thanks :)

You can enhance this example with a hook, to detect the screen width or screen width changes and act accordingly.
I extended your example: https://codesandbox.io/s/material-demo-forked-e1cro?file=/demo.tsx
const isBigScreen = useMediaQuery("(min-width: 1140px)", false);
const prevBigScreen = usePrevious(isBigScreen);
React.useEffect(() => {
if (isBigScreen !== prevBigScreen && isBigScreen !== open) {
setOpen((prev) => !prev);
}
}, [isBigScreen, prevBigScreen, open]);
My useMediaQuery hook with usePrevious is just an example. You can also use many other hook implementations.
