Ortur Laser 2, Laser doesn't work but everything else does

I have a Ortur Laser 2
I have it connected to a MacBook Pro
I open lightburn everything connects (so I think) I can move the laser anywhere I want I do a design and it moves like its engraving but the laser wont turn on.

I’m clearly new to all of this and just want to do simple stuff.
PLEASE HELP!

Thank you!
