 Because opentelemetry tracing initializer is not compatible with loco's default tracing initialization we must turn off the default logging.
 
+Follow the below steps in order to enable initializer:
+
+1) Add opentelemetry initializer to initializers list 
+```
+async fn initializers(_ctx: &AppContext) -> Result<Vec<Box<dyn Initializer>>> {
+    Ok(vec![
+        Box::new(loco_extras::initializers::opentelemetry::OpenTelemetryInitializer)
