breakout room button not displaying

[tapuat]

My Mac Zoom version is 5.17.11 (31580)

I am trying to be able to use the breakout room feature and the button is not showing up. 

I did activate it on my account.

I did reinstall the Zoom app. 

I checked that I use the same account on both the web and my desktop app. 

Still no button. 

FYI I have the PRO subscription.

What should I do?
