First Check

• [X] I added a very descriptive title to this issue.
• [X] I already read and followed all the tutorial in the docs and didn't find an answer.
• [X] I already checked if it is not related to AuthX but to Pydantic.
• [X] I already checked if it is not related to AuthX but to FastAPI.

Example Code

from authx import Authentication, MongoDBBackend
import motor.motor_asyncio
import asyncio

auth = Authentication(
    backend=MongoDBBackend(
        client=motor.motor_asyncio.AsyncIOMotorClient(
            'mongodb://localhost:27017',
            io_loop=asyncio.get_event_loop()
        ),
        database='authx',
        collection='users'
    )
)

Description

This should ideally create an auth object that can be used to include routers. Instead this gives an error

    backend=MongoDBBackend(
TypeError: __init__() got an unexpected keyword argument 'client'

Operating System

Windows

Operating System Details

FastAPI Version

Additional Context

This problem is arising as the MongoDBBackend class is not excepting any other parameters other than the database_name

class MongoDBBackend(BaseDBBackend):
    """
    Setup Database for authx using MongoDB & Motor
    """

    def __init__(self, database_name: str = "test") -> None:
        self._database_name = database_name

    def set_client(self, client: AsyncIOMotorClient) -> None:
        self._client = client
        self.init()

    def init(self) -> None:
        self._db: AsyncIOMotorDatabase = self._client[self._database_name]
        self._users: AsyncIOMotorCollection = self._db["users"]
        self._email_confirmations: AsyncIOMotorCollection = self._db[
            "email_confirmations"
        ]
        self._counters: AsyncIOMotorCollection = self._db["counters"]

        self._settings: AsyncIOMotorCollection = self._db["settings"]
