How to write to InfluxDB2 using hivemq-influxdb-extension

Hi all,
I just set up a fresh InfluxDB2 (current version 2.2) and created a bucket to collect some hivemq metrics.
As far as I understood, writing to my bucket involves usage of the token, which was created during database setup …
The only way to do so I found out in hivemq-influxdb-extension configuration is to use

mode:cloud

and properly configure the token and organization to use.

When trying to write to the bucket I get following error:

c.i.m.influxdb.InfluxDbReporter:258      - Unable to report to InfluxDB with error 'Unsupported or unrecognized SSL message'. Discarding data.

Taking a brief glance to hivemq-influxdb-extension source code, I realized that hivemq-influxdb-extension uses https to write data (which makes somehow sense if writing to a cloud via internet …).
Now, my database is local, why i haven’t enabled https.

Hm …, so I tried the other way and configured:

mode:http
auth:my-username:my-secret-password

Doesn’t work either, this time I get the following error:

c.i.m.influxdb.InfluxDbReporter:258      - Unable to report to InfluxDB with error 'Server returned HTTP response code: 401 for URL: http://influxdb:8086/write?db=spotcontrol&precision=s with content :'Unauthorized''. Discarding data.

I guess, because InfluxDB does not support this kind of writing since version 2.0 …?

What would be your suggestion for this case?
