How to make it possible to cut out parts of blocks?

Flipping through the discord server robloxa I saw a man who did a cool thing, namely, he hovered the mouse cursor over the block then part of the block that he circled moved, I want to do the same thing, but that the desired part was removed, that is, you circled part of the block and it was removed and fell, the question is how to do it?

P.S. Alas due to file size limitation I can’t show the video
