using Delphi TMongoUpdate to locate a Mongodb document using the default Mongodb ObjectId

I'm using Delphi 10.3 in order to access a MongoDB database. I'm trying to update a specific Mongo document using the ObjectId and having a hard time figuring out the exact syntax:

var
  MyMongoCollection: TMongoCollection;
  MyMongoUpdate: TMongoUpdate;
begin

  MyMongoCollection := FMongoDB.Collections['suppliers'];
  MyMongoUpdate := TMongoUpdate.Create(FEnv);

  MyMongoUpdate.Match('{_id : ObjectId("600aebbc329bc11e440063d1")}');
  MyMongoUpdate.Modify('{"name": "new supplier name"}');
  ...

I have tried all combinations to no avail. Can anyone help?
