Can I change the font size of a Label?

Is there no way to change the font size? I can’t find a reference in the docs:

https://sdkdocs.roku.com/display/sdkdoc/Label

Label has a documented font field. If you need to use something other than the built in system fonts, then you can add a Font child element with the role set to “font” (as in the first example here), or you can configure it in code.
