I'm trying to create a Story Map Tour using an existing online map. In the FAQ, it says:
Can I assemble content in my GIS and then publish it as a Map Tour?
Yes. You can create a layer that uses the set of fields that the Map Tour expects, add it to a web map, open that web map, and then share it by creating a Story Map Tour app. The Map Tour Builder will recognize your layer and use it to define the Tour.
But there's no description of which fields the Map Tour expects, and I wasn't able to find a blog post or GeoNet post explaining it. Thanks in advance for any help anyone gives!
