Default What is an "egg" actually doing in a flour recipe (onion rings)anyway?

My kid and I am just learning how to cook, and I keep seeing these
recipes that call for "an egg".

For example, we were making onion rings today and found this:

Seems to me, except for the seasoning, the egg & milk aren't
any better or worse than equivalent amounts of water ... but
maybe I'm missing something.

QUESTION: What 'does' the egg actually do in these recipes?
