Is there a clean way to invoke a common Architect flow from multiple inbound call flows without duplicating the logic? I tried using a Data Action with a REST call to the /api/v2/architect/flows/{flowId}/executions endpoint, but it returns a 403 Forbidden error. The token has the architect:flow:execute scope, yet the response payload just says "message": "Access denied". Does the API support this pattern, or am I missing a specific permission?
