How to access a shape's 'text' property in .json theme file and add a font

[Anonymous]

Hello, 

I need to add a font in the theme to be available in the Text property of any shape object (the one highlighted in the image below)

I can access the rectangle object via 'shape' visual object, but I don't know what are the other properties to get to add a font. 

I tried the following code, but it doesn't work:

"visualStyles" : {
"shape" : {
  "*": {
     "text": [{"fontFamily": "Ogg Regular"}]
       }
          }
                 }

It seems that line 

 "text": [{"fontFamily": "Ogg Regular"}]

isn't correct, and here is where I need help. 

I couldn't see in the documentation any cardName property that looks like the one I need. 

Do you know how can I reach this property and add a font?

Thanks

Hello, I couldn't make use of the solution that appears in the link. I need to add a new font to the Text section of a shape object. 

The question is what card property to I have to access in the .json in order to get to the Text section and add the font, if exists.
