i complete all required steps in the data 360 & agentforce playground for the challenge "Bring external data into the contact page layout". I added the data cloud profile related records component to the contact lightning record page, saved it, and activated it as org default. However, the component does not render on the contact record and verification fails with:"We can't find the external guest data stream for external data." this appears to be a backend trailhead playground configuration issue.
