Use Styles/StyleThemes in Thingworx Extension Project

Hello,

Is there anyway we can utilize StyleTheme Entity Services, in ThingWorx Extension Project.

We can define and use a parameter for Infotable, Thing, ThingTemplate/Shape etc.
But nothing from the Visualization group.

I want to utilize the StyleTheme to be able to pick the style properties, like the Font Name size and colors in the extension.

NOTE: This not about a Widget Extension

Thanks in advance.

Regards,

Bhushan
