Below is the bulkWrite method where I am inserting 1000 docs. The issue is I could not able to extract total upsertedCount from the results.

what I get those are individual BulkWriteResult like below for each inserted document

`console.log(results) :->

  BulkWriteResult {
     insertedCount: 0,
     matchedCount: 0,
     modifiedCount: 0,
     deletedCount: 0,
     upsertedCount: 1,
     upsertedIds: { '0': new ObjectId('6684fe4d1625ae49f6233577') },
     insertedIds: {}
   }

`
I will appreciate if someone come up with the solution.
method->

`db.collections.bulkWrite([
     {updateMany :
       {
        "filter": {"name": product.name}, 
        "update": {"$setOnInsert" : {
         name: product.name,
         description: product.description,
         price: product.price,
         category: product.category,

          }},           
         upsert: true
        }
       }
     ],{ ordered: false } )
  .then(results => {
    console.log(results)
  })
 .catch(err=>Error(err))`

I searched in mongodb docs where I could not found any solution in their docs about how to extract total upsertedCount.
