Data Action API 429s on minimal load

How do I correctly to handle 429 errors on the Data Action API? running JMeter 5.6.2 with just 5 threads against Genesys Cloud BYOC Edge 24.1.0 in Asia/Singapore. testing basic create/update calls and hitting limits immediately. getting HTTP/1.1 429 Too Many Requests even at low concurrency. any idea why?
