Hi @bbenameur , just a quick heads up: we are about to merge this PR that changes the API a bit. In summary, it offers more options to filter by date ranges, including CreatedAt (which you added via your PR), UpdatedAt and FinishedAt, on top of a few more filters.

This will change the API in the following way (example):

https://localhost:5001/elsa/api/workflow-instances?TimestampFilters=[{"Column": "CreatedAt", "Operator": 1, "Timestamp": "2024-02-16T00:00:00"}]

Notice that for the date ranges, we now have to provide a TimestampFilters parameter when using GET requests.
The API was updated to also support POST requests, which makes it simpler to post these filters.

Please let me know if you have any questions or concerns about this upcoming change.

Thanks again for your contributions!
