Thanks for sharing, is it you suggest that enhance the Easydiscuss polls system to be similar to this layout (screenshot: https://monosnap.com/file/yCaIV9kr4D3CpAw6UXlgc5NHNRstzP )? So the poll system can able to allows users to select from different presentation themes?

Or do you mean that you can consider integration with the Mentimeter about the live poll similar to what they developed this integration with Microsoft Team? https://www.mentimeter.com/microsoft-teams

If you are referring to the second option, currently I can't answer you whether this can be achieved or not since I do not see any development documentation from the website.

The only possible way is you can embed their poll presentation slides on the webpage. According to their video, I think the user does not need to have a Mentimeter account and also can vote on this.
