I'd like to create a style to applied to maps. Starting with an OS would be fine, but I can't figure out how to edit any features of the map in Pro. I've looked at a lot of documentation and videos and none of them quite walk me through what I'm seeing. My Contents pane shows Drawing Order > Map > The name of the map, but there are no editable attributes. I can't choose buildings or roads, etc. in order to edit how they appear on the map. What am I missing?
