I used a test imge with the latest downstream to test this feature, after I change the DiscoveredCluster type to ROSA and importAsManagedCluster to true, it successfully pass the check in here and trigger the auto-import-secret creation. The auto-import-secret includes the values we need, you can see it contains the client_id and client_secret instead of api_token:
