      1. What would you like to communicate to the user about this feature?
      2. Would you like the user to see examples of the syntax and/or executable code and its output?
      3. Which versions of the driver/connector does this apply to?

      Context

      The Interface for initializing Langgraph docstore is too cumbersome from developer experience perspective. It requires the user to init a connection and pass that to the initializer. Also to pass database and collection is slightly unituitive

      Given we haven't released it publicly, let's simplify it. 

       

      Current:

       

      mongo_conn_str = "mongodb+srv://***@xx-xx-dev.uruhxxx.mongodb.net/?retryWrites=true&w=majority"
mongo_client = MongoClient(mongo_conn_str){}

# init requires pymongo object imports
store = MongoDBStore(
    collection=Collection(
        database=Database(name="test-database", client=mongo_client), name="test-coll"
    )
)

      DOD

      The IDEAL Interface would be this:

       

      store = MongoDBStore(conn_str = , database_name = , collection_name = , index_config = {},....)
ex:
store = MongoDBStore(
    collection='test-coll',
    database='test-database',
    mongo_client=mongo_client,  # or even just a connection string here
    index_config={
        "embed": embedding_model,
        "dims": 1536,  # Embedding dimensions
        "fields": ["food_preference"],  # Fields to embed
        "filters": None
     }

 )
