GCP integration with Rapid 7

Does anyone has experience integrating GCP with Rapid 7. GCP event source is running however there is no data flowing in. We checked the Pub/sub and we can see the logs/message there.
Do we have any troubleshooting steps that we can follow to check if everything has been configured correctly.

Did you found it out eventually?

Also curious to understand the roles/permission you used.

Yes, it was a permission issue and you would require admin access to the project where pub/sub lies.
