How to select the first Component

I want to launch the editor with the style manager visible and populated. Meaning that a component is selected by default and the style manager shows the styles related to that selected component.

I have been struggling with how to access the model.

var domComponents = editor.DomComponents;

When I print the following to the console log, I see the models, I just cannot figure out how to access them. domComponents.getComponents()

I'd like to do something like: editor.select(domComponents.getComponents().models[0]); But that doesn't do anything.

I tried to print this to the console log: domComponents.getComponents().models it returns an empty array

I'm sure it's a simple answer but I've searched and attempted for a long time and can't figure it out, help is appreciated. Thank you.
