Hello. Once I've enabled break out rooms in Zoom how do I get them to work in a meeting?

Nice to see you again, *****!
Please allow me a moment to provide you with further instructions, I would really appreciate it if you would wait for me in the chat.
Start an instant or scheduled meeting.
Click Breakout Rooms.
Select the number of rooms you would like to create, and how you would like to assign your participants to those rooms: Assign automatically: Let Zoom split your participants up evenly into each of the rooms.
Click Create.
