Currently only 1 Zoom account can be connected to a Disco community at a time. Unfortunately this makes it difficult should you want different community admins to host different events. For example, what if the person who's zoom account is connected to Disco is unable to make the call and "open" the meeting.
The work-around is to first Create the event within Disco then login to Zoom and update the meeting settings to allow people to join before the meeting has started. In addition, add an alternative host for the second admin.
