You just try it yourself and go down the different lines. "Okay, Stockfish suggests this, but I wanted to do that, let's try my idea, oh, I didn't think of that response to my move". Etc., play along some lines, think about them. Sometimes it's obvious, other times it just sets up something far in the future you must be a grandmaster to see the subtlety of.
The Square One Chess channel on youtube turns this kind of exploration/commentary into quite digestible content, though the thumbnails are, like everything else these days, a little clickbaity.
It's been fun viewing for me and my chess-interested 9-year-old.
