[receiver/datadog] Grafana Cloud Operations table is not detailed by endpoint

Describe the issue you're reporting

Context

Having the following scenario

 +-------+           +---------+         +-------+         +--------------+
 | App A |     ->    | DD Agent |  ->   | OTelcol |   ->   | Grafana Cloud |
 +-------+           +---------+         +-------+         +--------------+

where

• Application A is a Datadog instrumented application
• DD agent sends telemetry and traces to an additional endpoint
• OTel collector is using Datadog's receiver
• Data is ingested into Grafana Cloud using OTLP.

Issue

In Applications > Services > Operations table in Grafana Cloud, a detailed view of each request resources shows a consolidated view of all endpoints under an operation type entry, instead of a detailed list of endpoints or resources.

The official documentation states that the resources are derived from the span_name field in each trace.

It seems that the span is translated and the endpoint is added in a span attribute.

Is there a way to achieve the detailed view using this schema ?

BTW: Having the same app natively OTel instrumented yields the desired result, as seen below

@ffapitalle can you attach a (few) span(s) that was forwarded to cloud? I want to understand what other attributes we could use to rewrite the span name. Ideally we'd evolve and use an equivalent to http.route etc
