Using the new C# 2.0 driver, I cannot seem to figure out how to run an Explain query.

An example query is:

var obj = await someCollection.Find(Builders<SomeType>.Filter.Eq("field", "value")).FirstOrDefaultAsync();

someCollection is of type IMongoCollection<SomeType>.
the Find command returns an IFindFluent<SomeType,SomeType> but this object has no Explain() method.

I am importing the following namespaces:

using MongoDB.Bson;
using MongoDB.Driver;

I am trying to do this without using the legacy driver but cannot figure out how to do it even with the legacy driver without creating a legacy connection since my Database connection returns an IMongoDatabase and none of the find options returns a MongoQuery.
