MongoDB Visual Studio Code extension: how to find by ObjectId - mongodb

Question

I'm using the following extension:
https://code.visualstudio.com/docs/azure/mongodb
To perform queries and light data transformation against a Mongo database. I'm having trouble working out how to issue a find request which matches an ObjectId.
I tried:
db.Epochs.find({
'ModelId': '624616797870316ac1432d52'
}).sort({'End': -1})
This results in an empty result set (this ID definitely exists because I copied that value from Compass.
I tried:
db.Epochs.find({
'ModelId': ObjectId'624616797870316ac1432d52')
}).sort({'End': -1})
Which results in the following error:
Unexpected token, expected "," (15:23) 13 | 14 | db.Epochs.find({ > 15 | 'ModelId': ObjectId('624616797870316ac1432d52') | ^ 16 | }).sort({'End': -1}) 17 | 18 | //'EndLogs._impl': { '$exists': true}
I tried adding the NodeJS driver setup calls like:
var Db = require('mongodb').Db,
MongoClient = require('mongodb').MongoClient,
Server = require('mongodb').Server,
ReplSetServers = require('mongodb').ReplSetServers,
ObjectID = require('mongodb').ObjectID,
Binary = require('mongodb').Binary,
GridStore = require('mongodb').GridStore,
Grid = require('mongodb').Grid,
Code = require('mongodb').Code,
BSON = require('mongodb').pure().BSON,
assert = require('assert');
Which errors with:
Cannot find module 'mongodb' Require stack: - c:\Users\Ian\.vscode\extensions\mongodb.mongodb-vscode-0.9.2\dist\languageServerWorker.js
Finally I tried:
db.Epochs.find({
'ModelId': { '$oid': '624616797870316ac1432d52' }
}).sort({'End': -1})
Which errors with:
unknown operator: $oid
