Remarks

A better re-engagement UI can be built within a consuming application if the source application can provide more details about the re-engagement. By serializing the collection of UserActivity objects into a JSON string, you can then store them in a DataPackage and reconstitute them in the consuming application to provide more insight about the source application and the specific activities within the application that sourced the DataPackage.
