%% This is the <i>Amazon AppStream 2.0 API Reference</i>. This documentation
%% provides descriptions and syntax for each of the actions and data types in
%% AppStream 2.0. AppStream 2.0 is a fully managed, secure application
%% streaming service that lets you stream desktop applications to users
%% without rewriting applications. AppStream 2.0 manages the AWS resources
%% that are required to host and run your applications, scales automatically,
%% and provides access to your users on demand.
%%
%% <note> You can call the AppStream 2.0 API operations by using an interface
%% VPC endpoint (interface endpoint). For more information, see <a
%% href="https://docs.aws.amazon.com/appstream2/latest/developerguide/access-api-cli-through-interface-vpc-endpoint.html">Access
