Delete the binding that has been created in the previous task. Verify that the UPS variant also gets deleted. It's not obvious how to get access to the Service binding instance, but there are a couple of ways:

1) The external ID of the service binding instance will be stored in the shared UPS secret created by the config operator after the variant has been created
2) In our test we can assume that only one such binding exists and write a query that just returns that one service binding instance.
