How do you select a specific color or shape in a Pixelmator Pro document with AppleScript?

It’s great that Pixelmator Pro has added examples to it’s dictionary. I want to select a specific color or shape in a Pixelmator Pro document.

I referenced the dictionary for the “load selection” command.
–> tell the front document to load selection mode new selection
I think I need “tell the front document to load selection mode new selection”

I assume I need to pass parameters, but I’m unsure of how to do that? Anyone have suggestions?
