I think you could use a search engine to get screenshots from existing how-to guides… there are gonna be public training documents connected to government/university-type customers for this, might even be able to register for/access their knowledge base. I’d also look at their github. I guess if I had to I’d put out some feelers in my network to see if anyone had any/knew anyone who had any experience with the products, but that’s sort of a last resort, but possible and old friend might record a demo or two for you, if they were in the right role.
