WebRTC Media Transport Policy Ignored in Architect Webhook

Having some config trouble here… The Genesys Cloud Architect flow triggers a ServiceNow ticket via webhook, but the subsequent WebRTC session drops audio immediately. The payload explicitly sets transportPolicy to relay to force TURN traversal, yet the client logs show STUN-only connectivity.

The SDK version is 2.5.4. The mediaId links correctly in the initial handshake, but the media stream fails to establish once the screen pop logic engages. Is the webhook execution context overriding the media configuration defined in the interaction settings?
