The UI Designer Chest components in the scene will automatically find the Chest Menu and assign themselves to it when opened. The easiest way to get started with the Chest Menu is to simply spawn a “Chest” prefab from the Demo folder in your scene. When the player interacts with the chest through the Inventory Interactor and Interactable components, the Chest Menu will be opened and bound the the chest the player interacted with.

Important: This Chest Menu is one solution for making chest in a game, but it might not suit your style of game. Feel free to create your own kind of Chest Menu using advantage of the Inventory Grid (or a custom Item View Slot Container) and other UI component. You may also want to create a custom Chest component if you decide to create a custom Chest Menu.
