"Export As" functionality in Product structure Editor

I would like to clarify the behavior of the “Export As” functionality within the Product Structure Editor. Could you confirm whether this option is simply downloading the already available derived outputs (e.g., *.stp files), or if it is actually generating new STP files?
Additionally, is the functionality capable of creating a monolithic STP file for an Assemblies?

I would also like to confirm whether additional licenses are required for this functionality. Specifically, does the system need extra licensing in order to generate files in different formats, such as STEP?
