For this tutorial, use the Brows_Up blend shape channel. Click the circle icon to the left of Brows_Up and select Set Brows_Up to get the SetBrows_Up node.

Option 2: Use Detection Nodes to Drive the Changes of Particular Blend Shapes of the Face

Instead of using the Start node, use different detection nodes to trigger facial animation. For example, use Eye Blink to blink your eye to trigger the animation to play.
