Green video icon on Mac menu bar not showing on MacBook

[bernieraffe]

When using Zoom on my Mac Mini computer, I have a green 'video' icon on the menu bar which I find useful.

But on my MacBook, that icon doesn't appear, instead I get a 'Zoom' text which has different functionality.

See screenshots for the two menus.

Menu bar with green icon 

Menu bar with text icon 

Both computers have the same 5.17.2 version of Zoom. 

Am I missing a setting, how can I get the green icon bon my MacBook.

Thanks for any help.
