Hi @KAxford,
To use Slido for Webex, your system administrator for Webex Meetings needs to enable Slido in Control Hub.
Otherwise, you could always use Slido as standalone via your browser after you log in to your account at slido.com
Also, the maximum number of participants allowed to join your slido session depends on the plan you’re on. With our free Basic plan, you can invite up to 100 participants to join your slido.
That being said, could you perhaps reach out to our Customer Care team at support@slido.com sharing more details about your setup so we suggest the best possible solution for you?
Kindly,
