Need help on how to engrave with Atomstack P7 40w

Hello, I’m new to laser cutting and need tips on how to successfully engrave clear acrylic with my atomstack, I have tested the machine but it passes right trough. I tested wood and it engraved beautifully. The current settings for power 20 and speed 90. Any assistance is much appreciated.

This video shows one way to achieve it.
