Support - Help organizing Spark home screen

I would like to know how to make the Spark home screen showing the users of my company’s conference groups! Showing who is currently online! Everything organized perfectly!

I know the image attached above is old, but this is what I’m looking for! An organization pattern!
I thank you for your attention!
Anyone who can help me…please!
good morning!

The organization in that screenshot is based on roster groups, not conference rooms.
