How to leave a course without leaving Zwift application?

Hello. do you know if it is possible to leave a course without leaving application ? because when I want to leave a course the system is proposing only : " register and leave" or “bean” and for these 2 options the Zwift application is closed. So if I want to do another course I have to re open Zwift application !!

At present you can’t do this. It is one of the most wanted features though.

It is possible, when using ZCA - meet-up.
You can choose world and route, start event, leave event. You must invite someone, but he/she may not ride (some users just set another account for this).
