I'm thinking the answer to this question is no, but I wanted a solid answer. I just want to know if you can self-host the new ArcGIS StoryMap (with the Classics, you downloaded the source code and inserted your app ID, so you could give it a custom URL, among other things.)
So far, I have not found a blog, article, question, or source code that gives me this option.
I tried asking ESRI chat, and they keep giving me links to the self-hosting the classics blogs from 2017, BEFORE ArcGIS StoryMap existed.
Is this an option yet?
