Delete a specific theme by id
This operation permanently deletes the identified theme from the database.
Because multiple themes can have the same name (with different activation time spans) themes can only be deleted by ID.
All IDs associated with a theme name can be retrieved by searching for the theme name with Theme Search.
Note: Custom themes needs to be enabled by Looker. Unless custom themes are enabled, only the automatically generated default theme can be used. Please contact your Account Manager or https://console.cloud.google.com/support/cases/ to update your license for this feature.
