Is it possible to use Calendar for JIRA for meeting room scheduling?

Hi! 
Our team recently started using JIRA Calendar because it mentions in the overview, that there is a possibility to have a "Calendar of meeting rooms - display the availability of meeting rooms, as well a tool for their reservation".

Has anybody actually used this or knows where to add the meeting rooms or the tool for reservation?

We have tried to just add the meeting rooms as separate calendars, but it is not too convenient to reserve them or overlook which rooms are free at what time slots.
