How to Map Standard operator properties in v2 DX api

How to Map Standard operator properties in v2 DX api for eg: pxCreateOperator is being passed by user from frontend (or i determine it from the token in auth either way) and i want to map the remaining properties for eg: pxCreateOpName on the case. How to do this? Is there an extension point in api/application/v2/cases or should i use the pyDefault of case type to map these properties.

To add some context, we are using DX apis to create cases in traditional UI kit. Not constellation.

@AshokC16992597 V2 DX API is supported, but it focuses on view-based authoring and requires that your application uses the React-based UI runtime. It works only with the Constellation Application. If your application is built on Theme Cosmos or traditional applications, you should use V1 DX API instead.
