recommendationsDisplayName property
The custom display name for the standard endpoint or user attribute (RecommendationItems) that temporarily stores recommended items for each endpoint or user, depending on the value for the RecommendationProviderIdType property. This name appears in the Attribute finder of the template editor on the Amazon Pinpoint console.
This value is null if the configuration doesn't invoke an AWS Lambda function (RecommendationTransformerUri) to perform additional processing of recommendation data.
