Hello there, coming from an Airflow background, I was wondering if there is already something built-in like an ExternalTaskSensor to declare dependencies between different flows like in Airflow?

I don’t think that’s exactly what I had in mind since this seems to trigger a flow from another flow
What I was expected to find is something like this https://airflow.readthedocs.io/en/stable/_modules/airflow/sensors/external_task_sensor.html
_Waits for a different DAG [/_Flow] _or a task in a different DAG [/_Flow] to complete for a
_specific execution_date [yeah ok not sure here since execution_date is a little different between Airflow and Prefect]_
this sensor basically pokes the Airflow database so that could be implemented in Prefect too by poking the graphql endpoint I suppose
