Как пропускать ряд если там уже есть данные? pygsheets

Делаю бота на aiogram. Пользователь вводит данные которые записываются в google sheets.
Как пропускать ряд если в нем уже есть данные? Есть ли какая то функция в pygsheets? Или придется делать ручками? Логика такая у каждого id юзера свой ряд.

UPD. Ошибка при append_table()
