How panelists can use Slido
When you launch Slido in a Webex Webinar as a host, Slido automatically opens in the Webex sidebar for all panelists. Panelists can then help answer submitted questions in Q&A and run polls during the webinar.
If you haven’t launched Slido yet, one panelist can open Slido from Apps or three-dot menu. As the host, you can overrun the panelist’s slido and add your own.
In case you’d like panelists to prepare polls in advance at slido.com, invite them to your slido as co-hosts before the webinar. This gives them access to set up Slido content ahead of time.
