Story arc sync with Scrivener (Mac)

I cannot work out how to get story arc in Aeon to sync to Scrivener (Mac). I have read all of the Sync Settings info in the Knowledge Base multiple times and searches user input, too. Can someone give me a step by step to set this up properly? I’m clearly doing something wrong. I want to be able to use the Subway Map view for story arcs in Aeon, and color code my story arcs in Scrivener using Label. So each event or passage is assigned a story arc in Aeon, and want it then to show up in the correct color and with the correct color label in the Label drop-down in the Scrivener footer when synced. Nothing I’ve tried is working, and it looks like it’s a basic function that ought to be simple. Help please!
