How to Trigger Argo Workflow When data.finish File is Created in Daily Directory (Using File EventSource + pathRegexp)?

[ThomasWork]

In our environment, there’s a module that creates a new directory every day (e.g., YYYYMMDD/), writes a batch of data files into it, and finally creates a completion marker file like data.finish in that directory.
We want to trigger a workflow every day when all daily data is ready. Should we use the File EventSource with pathRegexp configured to detect the creation of the data.finish file (e.g., .../YYYYMMDD/data.finish)?
