text: Based on the following context what are primary buttons used for? 1. Primary: A primary button should be used for the main action the user is meant to take on the screen or in a modal. As such, there should be only one primary button per page. (Example: A 'Submit' button accompanying a form.).
  1.1 Code: <aux-button label='Button'></aux-button>.
  
  2. Secondary: The secondary button should be used for actions that are important, but not the primary action. The Secondary Button is sometimes a direct alternative to the Primary Button (for instance a Cancel button coupled with a primary Save button), but can also be used on its own for individual actions.
  2.1 Code: <aux-button type='secondary' label='Button'></aux-button>.
  
  3. Tertiary: Tertiary Buttons should be used for actions that are optional and not a key function of the user's workflow. The Tertiary style may also be used when displaying several buttons together in order to cut down on visual noise.
  3.1 Code: <AuxButton type='tertiary' label='Settings'></AuxButton>
  
  4. Tertiary Subtle: Tertiary Subtle serves the same purpose as the tertiary button, but is presented in a subtle shade of gray for design scenarios that benefit from the button receding into the background. This variant should not be used without guidance from the UX Visual Design team.
  4.1 Code: <AuxButton type='tertiary-subtle' label='Settings'></AuxButton>
  
  5. Split Button: The Split Button combines a button with an inline menu to provide a primary call to action with multiple secondary options.
