Listen as agent

Establishes a server streaming connection that delivers tasks to taskable agents for execution. This method creates a persistent connection from Tasks API to an agent, allowing the server to push tasks to the agent as they become available. The agent receives a stream of tasks that match its selector criteria (entity IDs). The stream delivers three types of requests: - ExecuteRequest: Contains a new task for the agent to execute - CancelRequest: Indicates a task should be canceled - CompleteRequest: Indicates a task should be completed This is the primary method for taskable agents to receive and process tasks in real-time. Agents should maintain this connection and process incoming tasks according to their capabilities. When an agent receives a task, it should update the task status using the UpdateStatus endpoint to provide progress information back to Tasks API. This is a long polling API that will block until a new task is ready for delivery. If no new task is available then the server will hold on to your request for up to 5 minutes, after that 5 minute timeout period you will be expected to reinitiate a new request.
