Is Socket supported in the PPro ExtendScript environment?

[MARK3662717834h1]

When I try to implement the example from the documentation: https://extendscript.docsforadobe.dev/external-communication/socket-object.html
I encounter the following error:

Exception has occurred: 22

• Socket does not have a constructor

I know I can do this from the HTML/Javascript client side but since this was "advertised" in the documentation I was thinking it should be possible. Is there an ExternalObject library that I need to load to make it available?

I've not heard of a successful usage of Sockets from within PPro ExtendScript, and recommend doing that at the JavaScript level. 

Having said that...

This seems potentially useful/relevant:

Thanks for the quick reply. I think I'll just go with the JavaScript level.

On a related note: what ECMAScript version can be expected for the Javascript side of things on the latest release of PPro? I've detected ES7 level support with my current setup but I'm not sure if that's a reliable assumption across operating systems and recent versions.
