How to configure opentelemetry-collector

[l-rossetti]

Hello,

I really appreciate coroot CE and its straightforward installation by using Helm.

I have installed opentelemetry-collector and configured it with the suggested options I see in coroot "traces" tab, but even after that the traces tab doesn't show anything and says "This page only shows traces from OpenTelemetry integrations, not from eBPF. Integrate OpenTelemetry".
What am I missing? Do I need to enable anything on coroot side? Thanks
