Can other meeting hosts, co-hosts, or participants help manage the BlueSky Timer?

Yes! Click the paper plane icon in the top right corner:

A box will popup within Zoom where you can "Invite Users to use App." You can select certain participants or all participants. The selected users can then help control the Timer, even if they haven't downloaded the app themselves.

Please note that invited users will only have access to the Timer during that one active meeting. If they want to keep using the Timer on their own, they can download the app here onto their Zoom account!
