Client event ideas (b2b tech)

my team (b2b tech) hosts a full day product feedback event with about 15 of our top clients. usually is a mix of presentations on roadmap, upcoming features, live polling, and options to jump in at any time and give feedback on the individual features / roadmap

we got feedback recently that they’d like it to be more interactive and open ended rather than us “just presenting to them”. Again I think the live polling and culture of interactivity does some of this, but what other ideas do folks have to help get people talking and/or structure a more open ended conversation about what they want to see?
