Hi, if I schedule a flow to execute, say every 1 hour, through serve api, my terminal calling the python Prefect code is hung to run that Prefect flow. If I ctrl + c to exit, the flow will stop running. If I have 100 flows, then I will have 100 hung terminals. There has to be a better way to schedule once and only manage the scheduled flows on the UI. How could I do it? Thank you
