What each ingredient does

Egg whites
Whipped into foam to give the icing its light, airy structure and gloss.
Confectioner's sugar
Sweetens the icing and dissolves into the foam, helping it set smooth and firm.

The step that matters

Beating until smooth and glossy. Beating the sugar fully into the foamed whites dissolves the sugar grains and traps air evenly, giving a smooth, glossy icing rather than a grainy, weeping one.
