Hitting 405 Method Not Allowed when POSTing to /api/v2/messaging/conversations/{conversationId}/typing. The docs show this endpoint for external contacts, but the response body is empty. Tried adding x-genesys-org-id header with no luck. Is this endpoint actually live for public sandboxes or is it still in beta?

"externalContactId": "ext-contact-123",
