Привет, поигрался с примером, давай добавим в useBlockBodyScroll флаг вкл/выкл. Просто не всегда нужно заблокировать скрол у боди при монтировании компонента, иногда это нужно сделать по флагу.

const body = getBodyElement();
const defaultOverflow = body.style.overflow;
const defaultPaddingRight = body.style.paddingRight;
const scrollBarWidth = getScrollBarWidth();

body.style.overflow = 'hidden';
body.style.paddingRight = `${scrollBarWidth}px`;

return () => {
body.style.overflow = defaultOverflow;
body.style.paddingRight = defaultPaddingRight;
};
}, []);
};
