When I was a kid, I dreamt a lot about what happened between those two movies, since Star Wars came out when I was 2 and ESB when I was 6. There were some comics sure, but I felt ripped off we didn’t get to see what happened between them (yes, the holiday special was a thing, but it didn’t help much). A lot of weird dreams on my part (which incidentally is probably closer to how AI works these days, just remixing my memories, adding some new details, and the fidelity isn’t as good as the original).
