[FeedBack Request] API doc is not match Java SKD

Hi!
I use the latest stable java version:29.4.0 and I want to update a line item, this is your example:
Stripe.apiKey =“xxxxxxx”;​

InvoiceLineItem resource =InvoiceLineItem.retrieve(“in_1NuhUa2eZvKYlo2CWYVhyvD9”,“il_tmp_1Nzo1ZGgdF1VjufLzD1UUn9R”);
​InvoiceLineItemUpdateParams params = InvoiceLineItemUpdateParams.builder().build();​InvoiceLineItem invoiceLineItem = resource.update(params);​

But I cannot use this code, the compilation failed, InvoiceLineItem don’t have the retrieve function. Is this reasonable? If not, could you update your API docs? Thank you!
