Live reactions from participants in Prezi

I see the new feature of participants uploading their reactions via text, GIF or image in a live event. Do they need to also have the Prezi desktop app for this feature to work? If not, how can I enable this feature for my next presentation?

Hi @Tracy_Chen, please note that this feature is available by live editing your content with Prezi Video, therefore, the Desktop Application would be needed to be installed on the computer of the viewer so they can type on screen and add gifs on the fly.

Hope this helps!
