Vector Tile Layer Display in Story Map?

Question

I have a story map I'm creating referencing the Hurricane Florence flooding in the Carolinas. Admittedly not as experienced with story maps.

I have the 500-year floodplain as a hosted vector tile layer. It shows up fine in the web map, but I can't get it to show up in the story map (map series builder). I'd like to have it as its own tab. I tried moving it to the basemap, too. Still, I can't get it to show up. The feature shapefile is hundreds of megabytes (even dissolved together), so I really need to get it to render quickly in the form of a vector tile if possible, ideally also showing up in the legend.

Help!

Thank you!

Yeah, I see that for other layers but not this one. Is the lack of corresponding feature layer the problem? If so, would including that cause it to lag badly?

In the web map editor, expand the options under the vector layer in the Table of Contents. There should be an option called “Show in Legend”

Started upload over from scratch. Seems to work now. Odd.
Maybe you could help me with one other thing -- how do you get a vector tile layer to show up in the legend?
