How to get the "Send report" feature useful?

Trying to get the “Send report” feature useful with duplicati-monitoring.
The default format seems not to be compliant with the spec provided by @ChristopherK .
All myreport submissions show up as “unknown” in duplicati-monitoring:

Should the default report format be user-replaced by a duplicati-monitoring friendly version? Has someone created such a template?

Any help will be appreciated!

I believe it is possible to create a report template to produce a format that is compatible with duplicati-reporting, but I can’t find a doc on what the format should be.

I believe so as well but couldn’t find the related doc either. Has anyone figured this out?
