[Python] Python NiceGUI / FastAPI App Insights Integration

I'm developing a NiceGUI application in python and wanted to add application insights to the app. I have been able to do this as I'm getting requests and telemetry sent no problem. The issue I'm having is that I cant seem to get my custom logging messages to send to app insights.

I've previously added the configure_azure_monitor and the same code at this link AppInsights Samples and tried it on my "login" page below but it didnt work. Below is my main app start page, where I call config.py which sets up some common things. Login is where the user goes to if there is no authenticated flag set for them. I'm using the opentelemetry.instrumentation.fastapi FastAPIInstrumentor which sends details to app insights for you, which is working fine. I just dont know how to get my custom log messages to send. Any ideas?

config.py

from services.keyvault_service import load_secrets_into_session, in_memory_secrets
from dotenv import load_dotenv

def config_dev_environment():
local_environment = os.getenv("LOCALDEV", "False") == "True"
if local_environment:
load_dotenv(".env")
os.environ["HTTP_PROXY"] = "http://localhost:18080"
os.environ["HTTPS_PROXY"] = "http://localhost:18080"


def load_app_config():
config_dev_environment()
if not in_memory_secrets:
load_secrets_into_session()

def configure_app_insights():
local_environment = os.getenv("LOCALDEV", "False") == "True"
if local_environment:
configure_azure_monitor()
else:
configure_azure_monitor(credential=ManagedIdentityCredential(),)

tracer = trace.get_tracer(__name__, tracer_provider=get_tracer_provider())
logger = getLogger(__name__)
FastAPIInstrumentor.instrument_app(app)


app.py

from nicegui import ui, app
