Hi @ChandanChainani 👋🏻

Thanks for your contribution 🙇🏻

Before we can proceed with reviewing this, the PR needs some tests. Please add a test suite that covers the use-cases involved by the use-cases this introduces.

Also note that console is a Web API, and while the current implementation (I think) is not strictly complying with the specification, taking inspiration in the web platform test suite for this operation might be a good (yet not mandatory; until we decide to/proceed with making console specification-compliant) idea and starting point.
