Error: Requesting username even though I provided the api key

[nalakawula]

Hi, thank you for the library. I follow your README, and got following error:

Traceback (most recent call last):
  File "/home/sumar/Projects/python/fastapi-todo-convoy/convoy_test.py", line 2, in <module>
    convoy = Convoy({"api_key":"redacted"})
  File "/home/sumar/Projects/python/fastapi-todo-convoy/venv/lib/python3.10/site-packages/convoy/convoy.py", line 22, in __init__
    self.applications = application.Application(config)
  File "/home/sumar/Projects/python/fastapi-todo-convoy/venv/lib/python3.10/site-packages/convoy/api/application.py", line 11, in __init__
    self.client = Client(config)
  File "/home/sumar/Projects/python/fastapi-todo-convoy/venv/lib/python3.10/site-packages/convoy/client/client.py", line 12, in __init__
    self.username = config["username"]
KeyError: 'username'

Step to reproduce

• create python venv
• pip install convoy-python
• create simple python file

from convoy import Convoy
convoy = Convoy({"api_key":"your_api_key"})

• then run the python file.

Thanks
