Thanks a lot for your answer. So free and bought content from the marketplace counts as “licensed”? I am aware of the marketplace FAQ but I am asking because in the marketplace guidelines it says under section 1.1.e:
Products must not contain or be marketed using any copyrighted or trademark protected names, branding, or content, including any Epic-owned trademarks (such as game titles, logos, or character names), unless owned by or adequately licensed to the publisher.
