How do you create a destination to IoT built in services

I'm trying to create a destination to the IoT built in services as shown in the HANA Academy video:

SAP HANA Academy - IoT Services: Built-in OData [2.3.0] - YouTube

I'm able to access the data using the URI in a browser, however when I attempt to access the destination using the template wizard in WebIDE I get an Unauthorized error.

I'm not sure if I've missed some configuration step (I haven't missed anything in the video series), something has changed or it is an error.  Can anyone point me to a description of how to do this?

Thanks,

Ross
