Missing traces

Hi,

I send github traces to gcp using the following [github action](https://github.com/paper2/github-actions-opentelemetry?tab=readme-ov-file)
I can see all github traces in the gcp trace explorer but they are not visible in the grafana where I use this Google Cloud Trace plugin. I can see that traces from other sources are visible in grafana so it means my plugin is configured correctly. Many filtering methods have been tested.
I didn't notice anything unusual in the format of my github traces.
Do you know what may be the root cause of my issue? Are there any requirements for trace format?

Any advice appreciated.
