Final answer:
When a Virtual Agent or Workspace notification lacks a content provider or certain fields, a Placeholder Template is used to compensate for the missing information with predefined placeholders.
Step-by-step explanation:
For a Virtual Agent or a Workspace notification that doesn't have a content provider or is missing some fields in the content provider, you would create and use a Placeholder Template. This is a design that allows for the substitution of missing information with predefined placeholders or default text. The Placeholder Template serves as a fallback method to ensure that the notification still conveys the necessary message in the absence of certain data.
