[Python] Applications insights in an azure function app - metrics and custom dimensions missing

I have some trouble adding logs from an azure function app to application insigths. I am using this code:

import azure.functions as func

import requests
from settings import settings
from services.exchangerate_service import ExchangeRateService

from azure.identity import DefaultAzureCredential
from azure.monitor.opentelemetry import configure_azure_monitor

logger.setLevel(logging.INFO)

app = func.FunctionApp()
@app.timer_trigger(schedule=settings.IBAN_CRON, arg_name="myTimer", run_on_startup=True,
use_monitor=False)

logging.info('The timer is past du3e!')

logger.info("Segato5", extra={"custom_dimension": "Kam_value","test1": "val1"})

meter = metrics.get_meter_provider().get_meter(__name__)
counter = meter.create_counter("segato2")
counter.add(8)


I get traces but not custom dimesions and no metrics:
