Analytics API 413 on 90-day interaction query

Hitting /api/v2/analytics/interactions/queries for a desktop widget. It’s throwing a 413 Entity Too Large on a 90-day span. We’ve stripped the select array and reduced groupBy, but the body still chokes. Here’s the payload: {"dateFrom": "2024-01-01T00:00:00Z", "dateTo": "2024-03-31T23:59:59Z", "groupBy": ["queue.name"], "select": ["conversationCount"]}. Tried breaking it down: set start/end, loop while(end > start), then merge results. Totals duplicate though. Docs only mention result pagination. How do you chunk the date range properly? Not sure where to slice.
