Motion design, cloner and Boolean problem?

I want to create this with the new motion design tools in UE 5.5:
Naver Welcome Media: Create. Boost. Interact.

Can anyone help me figure out the steps I should take to get this done?
I created the scene I want with a cloner (grid setup), and now I want to bring in an object or text that would subtract its shape from the cloner.

:pray:
