Copy selection

Hey again,

I found docs about the Selection object here
But how do I retrieve the current selection using the api?
I found code for using batchplay using _property “selection” but this doesn’t give me the selection object I can copy from.

If you just want to copy it, how does this work?

   "_obj": "copyEvent",
   "_isCommand": true

I will also have to deal with this when my hands get to jsx refactoring to a UXP
