🇩🇪 issue: E-Rechnung with softr

Has someone experience with the german E-Rechnung and Softr?

I want to manage all invoice-related things in softr. So for one invoice there is a record in softr databases. This record is connected to all invoice items.

If the clients wants a PDF I can simply use the softr generate PDF feature.

But what if I want to create the E-Rechnung Format? Has someone experience with that?
