Hi Ronald,
this specific scenario (web-based Design Studio from Query Browser) was not pre-configured in the trial, and it's also not mentioned in the demo script of the trial / CAL appliance.
ICF services for Design Studio and authorizations are not activated by default but you can of course play with those in your instances (see note 2289865).
Besides HANA Studio and AfO, also the Lumira client should work against CDS views via the BW extension. The extension is part of the 30-day Lumira trial (enable it on the remote desktop) or other licensed Lumira editions.
Best,
Joerg
