How do I download a file connected to a supplier invoice?

[SWICRIOT]

I get an Uri when fetching the SupplierInvoiceFileConnection but how do I download this? Since I'm authenticated through the FortnoxClient instance I expect there to be a method to fetch these files. I don't find any documentation, I've tried using the HttpClient within FortnoxClient but that does not seem to provide authentication to the request as I get a 403 response back.

Ok, I got it. I should use the ArchiveConnector and use the FileId I got from the FileConnection.
