Dynamic Dimensions/Cube Services

Hello everyone,

Trying to create dynamic dimension in v9.0 application, I'm not able to an option to do the same in the create dimension source type dropdown. Only seeing the following

Same issue with creating Dynamic Dimension in a Service Factory (see ss below)
Also not able to see any Data Binding Type setting on the cube in order to turn the into dynamic cube

Does anyone have any idea if I may be missing anything here, or does the dynamic cube/dimensions is something I have to ask OS to enable in my application?

Appreciate your time, thank you!
