[Bug]: OTEL metrics are not grouped in the dashboard #21239

Bug description

I've installed netdata-plugin-otel via apt, and it seems to work in collecting metrics. I am using opentelemetry in .net 8.

Image

Expected behavior

Somehow group them, perhaps by splitting by dot into sub groups, or at least under one opentelemetry group.

Steps to reproduce

Install netdata-plugin-otel, send some metrics.

Installation method

kickstart.sh
