You could try reading the linked paper. If I am reading it correctly, basically, we have atmospheric models for brown dwarfs and the presence of C2H2 and compounds cannot be explained by those models. So they think there are more complex atmospheric processes like aurora or lightning behind it.

Yeah I definitely attempted but stellar chemistry isn’t something I’d say I’m comfortable with particularly at the level required to comprehend a paper. That said, the subject is very interesting to me.
