# Agent 2 Agent events > Agent 2 Agent events supported in Integration Service, including the InvokeAgent Task Completed event that Maestro uses to wait for long-running agent tasks. The Agent 2 Agent connector supports the following event: * InvokeAgent Task Completed When the remote agent answers the [Invoke an Agent](https://docs.uipath.com/activities/other/latest/integration-service/uipath-google-agent2agent-invoke-an-agent) activity with a task instead of an immediate reply, Integration Service polls the agent for the task status. The event occurs when the task reaches a final state, and Maestro then continues the process with the task result. :::note This event is available only in MaestroTM. :::
