fetching deselected items from array with react Hooks

I am trying to store unselected items from checkbox selection table. currently selection and deselection is working as expected even when navigating other pages with pagination but I need to get deselected items from the checkbox selection table.

This is my header checkbox selection handler fun

const selectAll = (e) => {
     if (e.target.checked) {
                    const dataIds = data.map((a) => a.id);
                    const filteredIds = dataIds.filter((id) => !allCheckedItems.includes(id));
                    const checkedItemsCopy = [...allCheckedItems].concat(filteredIds);
                    setAllCheckedItems([...checkedItemsCopy]);
                    setIsSelectedAll((prev) => {
                        return { ...prev, [pagination.page]: 1 };
                    });
                } else {
                    const dataId = data.map((a) => a.id);
                    const checkedItemsCopy = [...allCheckedItems].filter(
                        (prevSelected) => !dataId.includes(prevSelected),
                    );
                    setAllCheckedItems([...checkedItemsCopy]);
                    setIsSelectedAll((prev) => {
                        return { ...prev, [pagination.page]: 0 };
                    }); }}

I have a requirement if user deselected items from the page those unselected items I need to save in my deleteitem array. can some on tell. How Can I store deselected items.
