FlightFX Vision Jet checklist

In the integrated checklist, item 10 in the Before Taxi checklist instructs you to press the TOGA Button. I’m assuming that’s on the throttle handle somewhere but I’ve pressed everything on and around the throttle and I can’t seem to find the Button, nor do I know how to determine if it has been pressed. There is (I think) a button on the Pilot side of the throttle handle but pressing that doesn’t seem to have any effect.
I just skip over this step and proceed, but I’d like to know if I’m missing something. Thanks!
