mongodb - How to filter fields from a mongo document with the official mongo-go-driver

Question

How can I filter fields with the mongo-go-driver. Tried it with findopt.Projection but no success.

type fields struct {
    _id int16
}

s := bson.NewDocument()
filter := bson.NewDocument(bson.EC.ObjectID("_id", starterId))

var opts []findopt.One
opts = append(opts, findopt.Projection(fields{
    _id: 0,
}))

staCon.collection.FindOne(nil, filter, opts...).Decode(s)

In the end, I want to suppress the field "_id". But the documents didn't change.
