GCS Notifications not shown in Pub/Sub Topic message

Question

We have a GCS bucket named 'testfiles' and Pub/Sub topic 'testtopic' with a subscription 'testsubscription'. We have created a notification configuration to receive notifications on the Pub/Sub topic for any event happening on the GCS bucket. When we run the following command to list the notifications on the bucket,

gcloud storage buckets notifications list gs://testfiles

we see the below output,

{
  "kind": "storage#notification",
  "selfLink": "https://www.googleapis.com/storage/v1/b/testfiles/notificationConfigs/28",
  "id": "28",
  "topic": "//pubsub.googleapis.com/projects/test-project/topics/testtopic",
  "etag": "28",
  "payload_format": "JSON_API_V1"
}

Also, we have provided the Cloud Storage Service account the Pub/Sub Publisher role.

Despite these settings, when we upload a file to the bucket 'testfiles', we do not see any JSON messages in the above mentioned topic/subscription (testtopic/testsubscription).

We tried to follow the documentation here

Please advise, if there is something we are missing.

You pulled the message from the GCP `PubSub` console and with a command line ? — Mazlum Tosun, Oct 31 '22 at 11:07
No I pulled the message through a standalone Java application code — Sabari, Nov 02 '22 at 18:44

The console (GCP console, console.cloud.google.com) was not displaying the Pub/Sub messages. However, when we connect to Pub/Sub topic's subscription through a listener code, it was able to receive the JSON messages without any issues.
