Is onSuccess recreated on each render?

export const useEditHemoglobinEntryMutation = () => {
  const dispatch = useDispatch();
  const queryClient = useQueryClient();

  const prevHemoglobinValue = useSelector(selectors.hemoglobinData.getLastHemoglobinValue);

  return useMutation(
    async (payload: HemoglobinLevel) => {
      await Api.editHemoglobinValue(payload.id, payload);
    },
    {
      onSuccess: async (_, entry) => {
        maybeShowModal(prevHemoglobinValue, entry.value, dispatch);
      },
    },
  );
};
