https://github.com/googleapis/googleapis-gen/tree/master/google/cloud/gkeconnect/gateway/v1beta1/google-cloud-gkeconnect-gateway-v1beta1-java/samples/snippets/generated/com/google/cloud/gkeconnect/gateway/v1beta1

Steps:

• Try to generate gke-connect-gateway via the instruction in chore(bazel): [gsuite-addons] update protobuf to v3.21.7 #8549

suztomo@suztomo:/tmp$ git clone https://github.com/googleapis/google-cloud-java
suztomo@suztomo:/tmp$ git clone https://github.com/googleapis/googleapis-gen
suztomo@suztomo:/tmp$ cd google-cloud-java
suztomo@suztomo:/tmp/google-cloud-java$ module=java-gke-connect-gateway
suztomo@suztomo:/tmp/google-cloud-java$ GOOGLEAPIS_DIR=/tmp/googleapis-gen
suztomo@suztomo:/tmp/google-cloud-java$  docker run --rm --user "$(id -u):$(id -g)" \
        -v "$(pwd):/repo" \
        -v "${GOOGLEAPIS_DIR}:/googleapis-gen" \
        -w /repo \
        --env HOME=/tmp \
        gcr.io/cloud-devrel-public-resources/owlbot-cli:latest copy-code \
        --source-repo=/googleapis-gen \
        --config-file=${module}/.OwlBot.yaml

The command above creates:
