how to add a single sprite to an animation created in the inspector

Unity Engine

You have to specify what you want part of the sprite to animate in the animation, you can animate just about every property of a gameobject in an animation…

Basically I am trying to follow this solution How to create a blinking eye animation with 2 images - Unity Engine - Unity Discussions. The instructions are generally elaborate but I am not sure how to

“add each srpite to each animation (the open eye to one and the closed eye to the other one)”
