2023.3 - retrieve item from chiseled bookshelf

Hi,

The account returns 0 items in slot 0 whereas "slot_0_occupied"=true.

I think it's a bug because this function works with "normal" containers.

While I'm at it, is there an easier way to get the target slot?

Because apart from calculating the distance of the radius from the position of the block to retrieve the targeted slot, I don't see it.

Thanks in advance.
