-    registry-connect discover apigee products ORGANIZATION
-    registry-connect discover apigee proxies ORGANIZATION

-    registry-connect discover apigee products ORGANIZATION | registry apply -

-    registry-connect discover apigee products ORGANIZATION > apigee-apis.yaml
+    registry-connect discover apigee ORGANIZATION --project PROJECT_NAME > apigee-apis.yaml
     registry apply -f apigee-apis.yaml
