I have created a custon theme for my dashboard with a JSON file, where I specify the font family I want to use:
"fontFamily": "HP Simplified",
This works in all visualizations except on the button's text. I know I could change the font selecting the button and going to "Visualizations -> Button Text -> Font family", but the font I want to use is not available in the options.
I would really appreciate any ideas. Thank you!
