[QUESTION] Minimal requirements to create a custom component

I've been reading the docs all day on creating a custom component. I've also looked at grapesjs-mjml for an example. I'm trying to create a base type for react components that can be extended as needed, but at the moment all I want to see is which lifecycle methods are called and when. I'm trying to work out the difference between render and toHTML specifically. I've created just a bare bones component with some logging, and it doesn't seem to be working. Here is my code

import React from 'react';
export default editor => {
    var comps = editor.DomComponents;
    var defaultType = comps.getType('default');
    var defaultModel = defaultType.model;
    var defaultView = defaultType.view;
    
    // The `input` will be the Component type ID
    comps.addType('react-base', {
      // Define the Model
      model: defaultModel.extend({
          toHTML() {
              // we'll have to do some custom processing here
              console.log('toHTML')
          },
      },
      // The second argument of .extend are static methods and we'll put inside our
      // isComponent() method. As you're putting a new Component type on top of the stack,
      // not declaring isComponent() might probably break stuff, especially if you extend
      // the default one.
      {
        isComponent(el) {
          console.log(el); 
        },
      }),
    
      // Define the View
      view: defaultView.extend({
        render() {
            // Extend the original render method
            // we'll need to add some custom processing here too
            console.log('render');
            
          },
      }),
    });
      
      // A block for the custom component
      editor.BlockManager.add('react-base', {
        label: 'Test',
        content: (<div>Foo</div>),
      });
};

I'm passing a React component as the content, which I expect not to render currently, but I'm not getting a single log in my console either. I do see the custom block though so I know that editor is defined and exactly what I expect it to be.

I'm sure there is something very simple that I am missing but I don't know what it is.
