OH3 errors with inFluxDB

I did a fresh docker install of influxBD v2.1.1 and did the OH3 and InfluxDB configuration.
I found that I should use Authentication Token instead of username and password.
If I check the file influxdb.config it looks like expected.

When I check the file influx.cfg I see no configuration at all.
Is this file not used or should I configure this file manually?
