I recommend to enable "Dragonriding" in load tab, to see the Icons only while on a Dragonriding mount.
If you dont like the text "MIning" and "Herb" on top of the icon you can disable it in Display and turning off "text". You can change the size by clicking on the group and using "group scale"
I have used code from the excellent weak aura made by Funki - https://wago.io/jNjrKl3US
