Asset inventory view does not work for Serverless (security)

In the Elastic Security Serverless (GCP) we do not see data in the inventory tab (tech preview). this is the path in Kibana: /app/security/asset_inventory?sourcerer=(default:(id:security-solution-default,selectedPatterns:!(%27logs-*%27)))&timeline=(activeTab:query,graphEventId:%27%27,isOpen:!f)

I know this is only tech preview, but it would be great to get it working! I see a list of integrations, but we already have many of these integrations installed.
