What is the standard approach to handle authentication when triggering a WFM schedule publish from a Genesys Cloud Architect flow? We are using a custom Data Action to automate weekly shifts, but it returns a 401 Unauthorized error despite using a valid service account token. The WFM Admin role is assigned, yet the integration fails consistently at 2 AM CT. Is there a specific token refresh mechanism required for automated WFM calls, or should we switch to a webhook approach instead?
