CTRL F2 not highlighting menubar in mac

Hi! I cannot get CTRL F2 to highlight the menubar on Mac. It seems to have been fixed in https://github.com/electron/electron/pull/6068 (parent issue: [OS X] Ctrl+F2 keyboard shortcut to focus menu bar does not work · Issue #6016 · electron/electron · GitHub). From looking at documentation and help forums online, I am under the impression that it should work out of the box - but it isn’t. I am running Mac OS Catalina and Electron version 9.0.4. Could someone please advise on how to get this working?
