I have searched the forums as best I can, I have not been able to find an answer to this.
I would like to be able to create a new event in my calendar, invite attendees as I can see you can do, but also be able to invite a meeting room and a telephone conference line (for clarification see this from Google Gsuite Calendar - https://support.getjoan.com/hc/en-us/articles/115005866245-How-do-I-set-up-room-resource-calendars-in-G-Suite-Google-Apps-). Once the room and or conference line is invited it is reserved at the time. I am a little confused that you select an attendee and when you click on their name you can say select a Type, individual, group, resource, room or unknown.
I also require to be able to see their availability, I understand this is possible through an external client and coming to the web interface this year (a more defined date would be useful).
