Hello, this is a very noobie question but I cannot find documentation that answers this question specifically.
I have a collection with many objects that look like this

"name": "Phusaguaao-2",
          "class": "Gas3",
          "naturalResources": [
          "buildings": [],
          "resourceStorage": [],
          "production": [],
          "orbit": [],
          "hangar": [],
          "ownership": "unowned"

I want to be able to change the “ownership” property but I am stuck. I have created a single but I don’t see any way to connect it to the collection.
I’ve done this before with webhooks in node.js, but I am unsure how to start here.
Please just help me get started and I can figure it out from there.
I thank you in advance.
