I'm following the tutorial on developing an extra in MODX and I can't find any documentation on how to add a custom icon to the menu entry for my custom manager page.
In the tutorial there is only mentioned that it is possible (
see here), but not how.
Searching for other tutorials on how to do this brought up the fontawesome support that seems to work for templated resources, but the same approach does not yield any results on CMPs. Can anyone tell me how or point me to the well hidden documentation on this?
