Which fonts are automatically supported and which do you need to upload to Bravo?
If you have Figma
Any font supported in Figma would work. You would need to install Figma in order for it to be available for XD.
All other fonts
All other fonts require licenses for you to distribute. Therefore, you must have the font file yourself in order to use them in your apps. If you don't upload the font files, the app will display the text in a generic default font.
