Generate client stub for external dependency

[haf]

I want to generate a client for opentelemetry/proto/collector/trace/v1/trace_service.proto from here https://buf.build/opentelemetry/opentelemetry/docs/main:opentelemetry.proto.collector.trace.v1#opentelemetry.proto.collector.trace.v1.TraceService

I have buf.yaml:

version: v1

deps:
- buf.build/opentelemetry/opentelemetry

breaking:
  use:
    - FILE
lint:
  use:
    - DEFAULT

and buf.gen.yaml:

version: v1

managed:
  enabled: true

plugins:
- plugin: buf.build/community/timostamm-protobuf-ts:v2.9.1
  out: lib/grpc
  opt:
  - client_generic
  - optimize_speed
  - server_none

but when running buf generate, I only get these folders:

❯ ls lib/grpc/
google       node_modules

I understand that I'm not specifically referencing the service, but I also can't find how I specifically reference the service that I want to generate a client for. How do I generate a client for this file?

Create a client.proto like so

syntax = "proto3";

import "opentelemetry/proto/collector/trace/v1/trace_service.proto";

package causiq.sdkapi.v1;

and run buf generate --include-imports
