Ender 3D s1 pro laser module, no message for Z-Axis

Hi

I installed the laser engraving module. But when I “switched laser engraving” there should be a message to set the lowest point of Z-axis for laser focusing. But I don’t get this message so I’m not able to use the laser.

What did I do wrong? Can someone please help me out?

Thanks and have a nice day!
