Amazon WorkSpaces Application Manager (WAM) is now available in the EU (Ireland) region and has two modern management features. These modern features allow you to share application packages with other AWS accounts and delete packages within your AWS account using the Amazon WAM Studio. Package sharing allows you to virtualize an application one time, and share it with many AWS accounts. You can then customize the application configuration for each user to which the application is assigned using Configurable App Events.
