Can I hide the Attendance Taker but still keep it running?

You'll need to open the Attendance Taker app in each meeting where you'd like to take attendance, and it needs to stay open throughout the entire meeting to successfully generate your attendance report.

If you find the apps sidebar distracting, you can click the three dot button in the top right and select "pop out," so the Attendance Taker opens in a separate dialog box. You can then minimize the Attendance Taker while your Zoom meeting runs.
