Show in another color new features on layer

Question

Hello, i want to know if there is a way to show (in another color) new features on a layer that is being updated. So far i have found in the API for JS a event in the Dynamic and Feature Layer myDynamicMapServiceLayer.on("update-start",(us)=>{ console.log("is refreshing to show me updates?",us); });‍‍‍ For example, once i have been added the feature layer or dynamic service (in my case is a dynamic one) i want to put all the features that im showing in a certain color (lets say blue and they are 100 at the beginning). Afterwards, i want to put a glow on the one that are new in the place where they appear. Or have them as a data in a new table. Is there a way to do that?

Actually thinking in a not code based solution. I can just simply add a timing on the layer showing a diff kind of symbol when the feature is just added , and then change it again when the feature completes 1 min.

Well its like the objectid for that layer is not secuential. I was thinking about on save the prev state of the features that i have and then each time when the update-start on the layer see the differences between the old state and the new one.

Another solution would be to add those new features to a separate graphic layer and symbolize them differently.
