The Participation Tracker is just blank on the apps sidebar.

Sorry you're having trouble! Are you a host or co-host for this Zoom meeting? Currently the Participation Tracker requires that you be a meeting host or co-host in order to work properly.

You can request host or co-host status in a meeting to get instant access. Additionally, you can share app access with a host or cohost if you're looking for help managing attendance.

After opening up the Participation Tracker app, click the icon in the top right that looks like a paper airplane:

You'll then be prompted to share app access with All Participants or just certain ones. They don't even need to download the app themselves, and they'll have app access for this one meeting. Reminder that only hosts and cohosts have permission to use the Participation Tracker! If you share the app with a meeting participant who hasn't been made a cohost, the attendance list will be blank.

If your use case requires that you take Participation while not having host or co-host status, there is a workaround: we have a separate Meeting Timer and Attendance App that joins meetings as a Zoom participant. Because of this, it tracks participation in a different way, so it can track participation even if you are not the meeting host. You can install that app here.
