Hello. I am using the AWS CloudFormation <https://signoz-integrations.s3.us-east-1.amazonaws.com/aws-quickcreate-template-v0.0.4.json|template>. I want to get AWS services data to my self-hosted signoz.

It is possible to use some env variable to make all the requests for the logs/metrics/traces api send a custom header?

I tried to use <https://opentelemetry.io/docs/languages/sdk-configuration/otlp-exporter/#otel_exporter_otlp_headers|OTEL_EXPORTER_OTLP_HEADERS>, but I had no success. The image
```docker.io/signoz/cloud-integration-agent:v0.0.4```
has support for custom headers? I need to use one like *signoz-token* header because the signoz EC2 instance has nginx installed and it requires this token.

I can see my AWS account in the Signoz web UI, but the dashboards are empty. The ECS container agent shows:

```2025/07/02 20:00:25 failed to send logs to <https://mysignozurl.example.com/v1/logs>: 403 Forbidden (body: <html>```
The ECS agent must send the signoz-token header for each request.
