Step 2: Probe or look at the board to determine which trace carries the trigger signal and where you can pull the proper voltage from.
Step 3: Use the 555 timer method (https://www.instructables.com/id/Add-a-rapid-fire-button-to-your-mouse-using-a-555-/) (I know that it's for a mouse, but you can use it for this just as well). If you have access to an oscilloscope and can find the pwm line you could use a wire to that instead of the 555 timer method.
If you are still confused, I wouldn't recommend that you try to do this.
