Scheduling meetings on behalf group's calendar in desktop app

Hello, 

I have found a way how to schedule a meeting in Group calendar in Outlook online that the meeting is scheduled on behalf the group or it looks like. It is really useful for our scenario because everyone in group can edit the meeting. I would like to schedule the meeting the same way from desktop Outlook but when I add the calendar I am not able to do the same. How to set Outlook destkop, what to change or what to do that I can schedule it? When I schedule it in desktop and try to add another people it is always changed that the organizer is me.

Thank you

Mirek
