Quick question about Messaging API rate limiting in multi-org AppFoundry deployment

Quick question about handling 429 Too Many Requests responses when polling /api/v2/messaging/messages across multiple Genesys Cloud organizations. Our AppFoundry integration aggregates chat history for a unified dashboard, but we are hitting rate limits faster than expected despite implementing exponential backoff. Is there a way to increase the quota for partner apps, or should we shift to a webhook-based approach for real-time updates?
