Once you run the command to create the GCS notification, if the topic-name does not exist it will automatically create it for you. So your first step is to create a GCS notification, passing a topic name and the event type on OBJECT_FINALIZE as parameters.

Example:

gsutil notification create -t <TOPIC_NAME> -f json -e OBJECT_FINALIZE gs://BUCKET_NAME

Note the parameters:

-t = Topic name

-e = Event type (Object finalize)

Once this part is done, your next step is to create a subscription to view the notifications sent to PubSub. The subscription is attached to the topic created above.

In this documentation, it explains how to create a subscription and also a Node.JS example with a push delivery: https://cloud.google.com/pubsub/docs/admin#pubsub_create_push_subscription-nodejs
