Currently, Harness doesn't provide a way to see what version of the artifact is deployed in 'View in table' screen (pop-up window) for TAS artifacts.
It list out 'Service', 'Artifact', 'Infra/Gitops cluster' and 'Instances'. It doesn't provide other details like artifact version, and date/time of deployment.
Detailed view of what's currently deployed in environment for all the components is very helpful for various scenarios.
