Test Fire button

Hi, folks.
I have a Shapeoko 3 and bought the ‘LaserInk’ 4 watt laser.
I’ve been using the Object Works software but came across LightBurn recently.
Found the thread with a similar title and have tried several times to add the ‘Test Fire’ button to my laser control window but have not had any success.
Have any of you been able to get this option to show up on your screen?

Never Mind.
Just found it (Duh).
Thanks anyway.
