I've created a custom 2D symbol Style file (.stylx) in Arc Pro. I'd like to be able to access these symbols and symbol styles in AGOL, but according to the error messages that keep popping up, as well as these Esri resource pages (one, two), Web Styles are only intended for use in Scenes. Is this the case, or am I missing something? How would one go about using a Style in AGOL Maps (aside from publishing them inside a Web Map)?
