i want to remove the white pop-up background of mui’s default css.

 <Dialog
        open={open}
        onClose={() => {
          setOpen(false);
        }}
      >
        <DialogContent>
          <h1>are you sure to logout?</h1>
          <DialogActions>
            <Button>yes</Button>
            <Button
              onClick={() => {
                setOpen(false);
              }}
            >
              no
            </Button>
          </DialogActions>
        </DialogContent>
      </Dialog>
