You can create additional workspaces if you are collaborating with different teams. You can do this by navigating to your settings page and hover your cursor on "Workspaces". You can create as many workspaces as you want and each have their own users, security, billing and other administrative options.
When you have several workspaces, you can switch between them in the menu.
