When inserting a document how to automatically grab the current systems date in MongoDB Compass

Question

In a shell, I can do use new Date() as shown below:

db.myCollection.insertOne({
  ...
  "Last Modified Date": new Date()
});

How do I do it in MongoDB Compass? new Date() is not valid. <! Insert not permitted while document contains errors.>

{
  "_id": {
    "$oid": "xxxx"
  },
  ...
  "Last Modified Date": new Date()
}

I could manually enter the current systems date but I want it to grab that automatically when a document is inserted.

Thanks!

Tried below but no luck

• "Last Modified Date": new Date().toISOString(),
• "Last Modified Date": new Date().toISOString().split('T')[0] + ' ' + new Date().toISOString().split('T')[1].split('.')[0] + 'Z',
• "Last Modified Date": { "$currentDate": { "$type": "date" } },
