Can't find Activity Map function in StoryMaps

[GeorgeDurkee1]

Hi: I'm trying to put a gpx track onto a storymap. A StoryMaps Update from November 2023 shows it pretty straightforward (https://www.youtube.com/watch?v=vWZdcvalbYg&ab_channel=StoryMaps) with "Activity Map" in the + dropdown. I'm not seeing it, only Immersive as a heading and Side Car or Map Tour as options and neither seem to show a way to get a gps file.

I had worked out a way using the old AGOL Classic to just drag in a gps file, then convert to a feature layer (or use DNRGPS to create a shp file, publish as a feature layer, then bring that in but the Update 2023 video looked way easier and with more features.

What am I missing to get to Activity Map?

Thanks!

George
