Using arcade(?) to symboloize webapp with time-slider

[LyndaMccallum2]

Hi, I have a time slider webapp where we would like to show current time-step polygons in one color and any previous ones in another color. I’ve tried looking into arcade and it appears that arcade does not have access to the time slider properties). Does anyone know how to achieve this with or without arcade? Ideally, I would also want to be able to define which colors are displayed. Thanks

You can't really do that in a web map unless you get into some custom coding, like this:
