return new Promise(async (resolve, reject) => { db.get().collection('bbb1collection').find().sort({$natural:-1}).limit(1).next().then((res) => {
    console.log(res)
    resolve(res)
});
});

Check out this:

db.collection('bbb1collection', function(err, collection) {
  collection
    .find()
    .sort({$natural: -1})
    .limit(1)
    .next()
    .then(
      function(doc) {
        console.log(doc);
      },
      function(err) {
        console.log('Error:', err);
      }
    );
});

Use this query:

db.users.find().limit(1).sort({$natural:-1})
