Great work Rajarshee!

Please ensure you update the main README.md as well marking CCM as done and pointing to the installation instructions.

We also need a README inside the plugin with couple of screenshots. For example - https://github.com/harness/backstage-plugins/tree/main/plugins/harness-iacm

Can we add the annotation info here? harness.io/perspective-url

[rajarshee-harness]

@Debanitrkl @rajarshee-harness Let's ensure it works with

1. vanity urls (app3.harness.io, company.harness.io, etc.)
2. old and new nav urls both

We can't merge before that as it leads to confusion after deployment.

[Debanitrkl]

@rajarshee-harness here we need to add all the URLs that are available for perspective ID, like new nav old nav unified view, example
