Sugar REST API filter for data records that were created after a certain date.

Hello,

In a request to the Sugar API, I would like to filter for data records that were created after a certain date.
According to the API documentation, this should work with $gt.

However, my filter:

?filter=[{"date_modified":{"$gt"2024-03-06T16:56:16+01:00":""}}]

returns the error "invalid parameter".


What is the correct syntax? Can anyone help?

Thanks

Steffen
