Can I show a game name on YouTube without permission?

I posted a youtube video lately and there was the name of my old friend (the name was blurry) but he told me that and I said that I did that without permission but ytber also play Fortnite after laps when they die Do you show thousands of names? What should I do now?

I suspect that since he is more or less in public, he has no leverage.

You do not have to worry about showing an ingame name is not a criminal offense and can't be punished.

It is different with audio or facial images of your friend without his permission.

Thank you.
