Watching on mongoose document changes is broken after updating to latest version

Is there an existing issue for this?

Current behavior

At my backend I use @nestjs/mongosse: "9.0.2" and I have a piece of code which watches for changes as such:

watch.on('change', (change) => {
      onChange(
        change.fullDocument?.content &&
          !change.fullDocument?.read &&
          change.fullDocument?.last_sender_id !== userId,
  );
});

After trying to update to the latest version of the @nestjs/mongoose package I get the following errors:

Property 'fullDocument' does not exist on type 'ChangeStreamDocument<PostboxRoom>'.
 Property 'fullDocument' does not exist on type 'ChangeStreamDropDocument'.
399           !change.fullDocument?.read &&
                      ~~~~~~~~~~~~

It looks like the typing had a breaking change or something similar? How should we access the fullDocument now?
