Could someone explain the rate limit behavior for GET /api/v2/wfm/schedules? JMeter 5.6.2 hitting 429 Too Many Requests immediately at 50 concurrent threads against Genesys Cloud BYOC Edge 24.1.0 (Asia/Singapore). Trying to simulate schedule retrieval for 1000 agents but getting throttled after the first batch. Need to understand the exact bucket refill rate for WFM endpoints.
