Screen Recording API 429 during JMeter Load Test on US1

No idea why this is happening, the /api/v2/recordings endpoint returns HTTP 429 when pushing 200 concurrent threads. The environment is Genesys Cloud US1. We are using JMeter 5.6 to validate capacity.

thread_count: 200
ramp_up: 60s
endpoint: /api/v2/recordings
headers:
 Content-Type: application/json
 Authorization: Bearer <token>

Does anyone know the correct rate limit for this endpoint?
