Delete a single document from collection

Say I have the following in users collections (i.e. when I run db.users.find().pretty() I get the below)

{
	"_id" : ObjectId("5bd982dea18ceecf4bba3c47"),
	"username" : "test-user-2",
	"post" : "123456"
}
{
	"_id" : ObjectId("5bd983e4a18ceecf4bba3c48"),
	"username" : "[email protected]",
	"password" : "$2a$10$HyXCD5.4U/0CvZHq9SDQ0uxD12BQ46yVAHu18lRRVEQZB3uyHXgy.",
	"__v" : 0
}

And to delete just the top-most document with id of "5bd982dea18ceecf4bba3c47" run the below command

try {
   db.users.deleteOne( { "_id" : ObjectId("5bd982dea18ceecf4bba3c47") } );
} catch (e) {
   print(e);
}

And now running db.users.find().pretty() will give me just

{
	"_id" : ObjectId("5bd983e4a18ceecf4bba3c48"),
	"username" : "[email protected]",
	"password" : "$2a$10$HyXCD5.4U/0CvZHq9SDQ0uxD12BQ46yVAHu18lRRVEQZB3uyHXgy.",
	"__v" : 0
}
