Before you can use a workspace, you'll have to build it. To do so, switch to edit mode using the top-right "Edit layout" button.
Adding components to your workspaces

The Button Component
For now the Button component can only be used to trigger global smart actions; however, in later iterations, you'll be able to trigger any action from this button.
