I was directed here by Zoom Support. Currently, Zoom allows users to setup breakout rooms when creating meetings. However, when doing this via the LTI connection from Blackboard, this feature is not supported for meeting creation. See 2021-09-02_16-55-45 for a demonstration of the differences.
I would like to see Zoom support breakout group creation when creating meetings using the Blackboard LTI. This process should allow users to add students from the course in question directly into the breakout groups when creating the meeting.
