Header.Builder

public @NonNull Header.Builder addEndHeaderAction(@NonNull Action headerAction)

Adds an Action that will be displayed at the end of a header.

Note: End header action will show up differently inside and outside of map-based templates.

• In a Non-map screen (eg. MessageTemplate), actions appear as is, just as the app provides. A background color is allowed on the primary action.
• In a Map-based screen (eg. Setting Header in the ContentTemplate in a MapWithContentTemplate) only actions with custom icons or standard actions will appear in the Header. The label will be stripped off each action if an app still provides that. Any tint on the icon will be disabled and default to neutral token. The background color on the primary action would also be removed.
