EU DSA question for non-English developers with PO boxes

I have a question for fellow developers from non-English speaking countries who had successfully submitted the DSA form as traders on App Store Connect specifying a PO box as address.

I've read somewhere (likely on Mastodon) that Apple requires the PO box documentation to be "officially" translated in English to accept it.

I am 100% positive this is not something I would be able to get from Italian Posts, because the contract will only be in Italian.

How did you handle this?

Were you able to submit the PO box documentation in your own language?
