iCal Scheduling on Mac OS

[dowds]

Update to Version: 5.15.3 on Mac OS has had the effect of disabling iCal sharing capability. When scheduling, I'm unable to select an alternate calendar in the drop down window. 

Previously, when scheduling, iCal window would open and confirm the scheduled meeting.

I have the same request from Zoom tech support. How to recover the effect of scheduling a zoom meeting and Mac OS calendar would create it in the Mac OS calendar application? Please reply with a setting fix or suggestion.
