Slide in Menu prefabs place a menu object offscreen to the left. When a user pans from the left edge, the menu will appear. When the user pans back towards the left, the menu will close.

Select the menu target.

Set the menu's opacity when the slide in begins.

Set the length of the animation once the user finishes the pan.

Set the easing curve for the animation. Higher spring values add more bounce to the animation.
