hi all - I'm relatively new to signoz, but been working OTel for a bit inside an Elixir app. I spun up the signoz containers with docker compose, and can get to the localhost:3301 page. My app is showing me otel in the stdout, but I don't see any services in my signoz. My config.exs looks like this:

config :opentelemetry, :resource, service: %{name: "MY_APP_NAME"}

config :opentelemetry, :processors,
  otel_batch_processor: %{
    exporter: {
      :opentelemetry_exporter,
      %{endpoints: ["<http://0.0.0.0:4318>"]}
    }
  }

I'm not seeing any errors in any logs from the containers, so maybe I'm missing something altogether different?
