Fetching only updated records from a certain time in FHIR call

Is there a way to get the records which have been updated from a certain time. I tried to use _search and _lastUpdated as search parameters but got the error saying the search field doesn’t exist or is not supported.

I was making the FHIR call as below:
https://xyxx.xx/openemr/apis/default/fhir/Patient?_since=2022-10-06T20:51:05

I am still curious whether _since or _lastUpdated search parameters have been implemented in OpenEMR. I would like to get only updated records after the initial pull of patient records.
