Installing on Neon.3 Release 4.6.3 for "System Workbench for STM32"

[AdvancedNewbie]

Hi there. I am trying to install this to the "System Workbench for STM32" version of eclipse, however, in this version of the IDE the regular stop / 'X' buttons are missing in this IDE - and so there is no extra stop button added either after installing this plug-in.

Is there a way to map the functions of this plug-in to a keyboard shortcut, or maybe a toolbar 'Action Set Availability' or something?

EDIT: I see that if I switch to the openocd console I do see the button briefly, then it disappears as the focus changes regardless of unchecking the 'Window -> Preferences -> Run/Debug -> Console' options:
Show when program writes to standard out
Show when program writes to standard error

EDIT 2: The consoles are named 'CDT Build Console [ProjName]' and 'CDT Global Build Console'. No kill button on these.
