I am trying to listen to the input within the editor's rich mode, so I can generate a summary/abstract dynamically.

My plugin code look like:

const richTextAwarePlugin = realmPlugin({
  init(realm) {
      realm.sub(contentEditableRef$, (e) => {
        console.log("contentEditableRef$", e?.current?.innerText);
      });
      realm.sub(rootEditor$, (e) => {
        console.log("rootEditor$", e);
      });
  }
})

By applying this plugin, I noticed that the sub callback is executed once when the editor is mounted. The callback didn't execute on every input.

How can I achieve my expectation correctly?

append: I dont mean the markdown source which I can fetch by onChange callback. I mean the rich text mode text.
