l10n_fr_chorus_account - Discount on one item activates an xml line on other items

[PlantBasedStudio]

Hello,
I have detected an unexpected behavior when issuing invoices with the chorus module.
When I have a discount on one of my items and I have several items in the invoice, the module will consider that all the items have a discount, but as these are at 0%, the mandatory associated line (ActualAmount) will not appear for these items without a discount. This generates the following error:

Facture n°FAC/2024/0021:L'element (AppliedTradeAllowanceCharge.ActualAmount.value) est obligatoire si l'element (SupplyChainTradeTransaction.IncludedSupplyChainTradeLineItem.SpecifiedLineTradeAgreement.GrossPriceProductTradePrice) est renseigne.

Example of an item line with a discount:

Other items have the line AppliedTradeAllowanceCharge but no line ActualAmount.

I'm willing to correct this problem with a PR.
Can you help me find out where the file is generated and if I can control the editing of lines according to items?
