Can´t open Inventor Files

[Victory2k 0]

Hi. I was using older versions of Cura, passing files in STL format from Autodesk Inventor (now 2023) without any issues.
I updated to CURA 5.8 that claims has native integration with Inventor files (.ipt and .iam).
But I can't find how to load or import Inventor files.  .ipt and .iam are not listed in the open menu. If I select "all files" and try to open any inventor file, I get an error.
Thanks for the support !

Native import from CAD programs requires that you (or usually, your organisation) has an UltiMaker Professional or UltiMaker Excellence plan (the different plans are compared here).
