I'd like to add line features that are displayed when point features are clicked on in a shortlist Story Map, similar to the story map here that shows travel lines when you click on a city (select a candidate, then click on a city to see the lines that display). Is it possible to set this up in ArcGIS Pro, or would it require some developer-level changes to the Story Map source code? Any sense of how difficult that would be for a non-developer? It appears that the authors used Leaflet as well -- not sure if that would make it easier.
Thanks for any insight!
