Does Articulate Storyline support .odf files?

Title says it all. I don't have MS Office, working from Google and LibreOffice so using .odf file formats when I export. Does Articulate Storyline support these?

Related, it also seems like I have to own an MS Office license to be able to import Powerpoint slides into Articulate Storyline (desktop), even if I was sent a .pptx file that I can open via any number of means (google slides, adobe, LibreOffice Impress). Can anyone confirm this? The different options on the help page for Powerpoint slide importing issues: https://www.articulatesupport.com/article/Articulate-Storyline-360-Failed-to-Import-PowerPoint-Presentation
all seem to suggest that you should already have a Powerpoint license. Is this really the case?

Thanks!

PS: There doesn't seem to be a generic, non-360 tag in the content tags list, does Articulate not support questions about the desktop versions of their software?
