Where in SITL should be activated joystick (Xplane 12)

As question stated, where should be activated joystick when running SITL with Xplane 12?
Docs are contrary and at one place state that joystick should be in MissionPLanner, amd at other place it tells that it should be at Xplane

When I activate it in Xplane, heli stops responding to joystick input, and in a cockpit neither yoke nor pedasl are moving, just collective.
