Thank you Sjanni for your reply. I captured a photo in Adobe Capture and chose vector based image. That was stored in my library. When I opened Adobe Fresco, it listed the new brush as unavailable. I can only assume that Adobe Fresco can only access created brushes via pixel, which works well when I create an image via Capture as a pixel saved brush file. I thought since Fresco also has vector based brushes available, I could create a vector based brush for Fresco to use. I don't think that is available.
