It’s a while since I last did this but I recall I used my Britool breaker bar, eighteen inches long, 1/2” drive, with an adapter to a 3/4” drive hex, not bi-hexagon, impact grade socket. Supported the hub on an axle stand. Stopped it turning with a one metre or so steel bar bought from B&Q hardware section. Fixed bar to hub having drilled two holes in it spaced to fit over two of the wheel studs, other end resting on the floor. As mentioned above you must ensure you respect the handedness of the nuts. I remember that I expected it to be tricky and half expected I might snap the adapter at the torque level required but in practice it was no problem.
