Arcade - add function to grab layer name and id

[NiekGoorman1]

For popup expressions it would be really useful to be able to get the layer name and ID for a feature. I'm just starting to use Arcade and am trying to create dynamic URLs based on feature ID, for which I also need the layer ID, only to find that Arcade does not support this. It does allow extracting a featureset, which even displays the name or ID, but there is no way to dynamically extract this.

It'd probably require the creation of a new type, akin to the "Portal" type, but I agree that it would be very useful to be able to grab the URL or ID via Arcade.

Yes,  it would be really useful to be able to get the layer name and ID for a feature.  If you have these two items it would be really easy to create a URL to download that single feature as a KMZ file or JSON string and present the URL in the pop-up window.
