[PS 8.1] Show Additional Addressfields also in Backoffice

[leoCodesAShop]

Hi everyone,

I successfully added custom address fields to the front office using the additionalCustomerAddressFields hook, and everything works perfectly there. However, I'm facing an issue when trying to edit a customer's address from an order in the back office. The custom fields do not appear in the back office address form.

I attempted to use the actionAdminAddressesFormModifier hook to add these custom fields to the back office form, but I couldn't get it to work.

Could anyone provide guidance or examples on how to properly add custom address fields to the back office address form using actionAdminAddressesFormModifier or any other appropriate method?

Thank you in advance for your help!
