 Interaction becomes possible using the S3IBAsyncClient Component and its get-, setValue and invokeOperation methods. Specific elements of the AAS are addressed through a path which has the following form:

 To await specific messages, S3IBAsyncClient's awaitMessage method can be used. This takes the message's attributes as parameter. In the following, demo2_forestmanager.py awaits a UserMessage with text "Authorized" that signals that access has been granted before proceeding with rest of the code.
 `await client.awaitMessage({"text": "Authorized"})`
