JSON File is imported for theme, fonts not updating

[Agam]

I am trying to use Roboto font in my pbix. I have created a json file. It says that import is successful. However, it just changes the colors. Font style remain as is. 
Below is the script I am using for json.
{
"name": "Theme",
"dataColors": ["#1a661f","#2b9630","#aac811","#F18643","#e52600","#73b0db","#335c73","#7E6996"],
"textClasses": {
"callout": {
"fontSize": 45,
"fontFace": "Roboto",
"color": "#252423"
},
"title": {
"fontSize": 12,
"fontFace": "Roboto",
"color": "#252423"
},
"header": {
"fontSize": 12,
"fontFace": "Roboto",
"color": "#252423"
},
"label": {
"fontSize": 10,
"fontFace": "Roboto",
"color": "#252423"
}
}
}

If it changes then it displays the "Times New roman" fonts but in visuals pane it will say "Roboto".

Please note that it is necessary to install the Roboto font on Windows (or any other font that is not preinstalled on Windows) before being able to actually use it in Power BI desktop.
