use this workflow to join a zoom-meeting using an ID or one of your bookmarks.
Add a meeting to your bookmarks. Enter zma <id>
first. Alfred will ask you for the meeting-password (you can, but you don't have to enter one) and the name under which you want to save it. You can pass an invitation url too.
Join a zoom-meeting. Either enter the id directly or choose one of the suggested bookmarks.
Delete a bookmark. Alfred will suggest the meetings you can delete.
