How can I detect a content control without the user selecting the whole thing?

Background

I've inserted a bunch of content controls into my word document. Each content control is a bit of text e.g. "Hello world".

What I'm trying to do

When a user puts their cursor within the content control I want to access the details of the content control within my add-in.

What I've tried

I run this at startup.

Office.context.document.addHandlerAsync(Office.EventType.DocumentSelectionChanged, () => {
    Word.run( async (context) => {
        const range = context.document.getSelection();
        console.log({range});
        const contentControls = range.contentControls;
        contentControls.load("items");
        await context.sync();
        console.log('contentControls.items', contentControls.items)
    })
})

Problem

If a user pops their cursor in the content control no "items" are reported. However if a user highlights the whole content control the "items" are correctly reported.

Question

Is there a way to detect if a user is within a content control without them having to select the whole thing?

Try using Range.parentContentControl (or parentContentControlOrNullObject) to get a reference to the containing content control.

For example,

  const parentContentControl = range.parentContentControlOrNullObject;
  await context.sync();
  if (parentContentControl.isNullObject) {
      console.log("The cursor is not in a content control")
  }
  else {
      console.log('parentContentControl', parentContentControl);
  }
