Starting With A Chest

Hey, so i just created a chest that i can put stuff in. Whenever you join a world the first time you start with the chest. Right now im just trying to find a way to put items in the chest, like. When you start a world. You start with a chest, and if you place it on the ground and open it. It has stuff in the chest, is that possible? Its kinda like a shulker. You can have the shulker with stuff in it with stuff in the shulker, but i created a chest and want to start with stuff in it. Is it possible
