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.

Thank you!
